The Evolution of Hemoglobin. by Ross Hardison
American Scientist March-April 1999 v87 i2 p126(1) Page 1 the evolution of hemoglobin. by Ross Hardison A comparative study of hemoglobin was conducted to explain how an ancestral single-function molecule gave rise to descending molecules with varied functions. Hemoglobin is the molecule in red blood cells responsible for giving blood its color and for carrying oxygen throughout the body. New functions of metallo-porphyrin rings or a kind of molecular cage embedded in proteins were developed with the appearance of atmospheric oxygen. The presence of hemoglobin in both oxygen-needing and non-oxygen needing organisms suggests the same evolutionary roots. © COPYRIGHT 1999 Sigma Xi, The Scientific Research If similar compounds are used in all of these reactions, Society then how do the different functions arise? The answer lies in the specific structure of the organic component, most Studies of a very ancient protein suggest that changes in often a protein, that houses the porphyrin ring. The gene regulation are an important part of the evolutionary configuration of each protein determines what biochemical story service the protein will perform. The appearance of atmospheric oxygen on earth between Because they have such an ancient lineage, the one and two billion years ago was a dramatic and, for the porphyrin-containing molecules provide scientists with a primitive single-celled creatures then living on earth, a rare opportunity to follow the creation of new biological potentially traumatic event. On the one hand, oxygen was compounds from existing ones. That is, how does an toxic. On the other hand, oxygen presented opportunities ancestral molecule with a single function give rise to to improve the process of metabolism, increasing the descendant molecules with varied functions?

Since severely ill patients often show elevated methemoglobin (MetHb) and carboxyhemoglobin (COHb) concentrations in their blood as a marker of disease severity, we aimed to summarize the currently available published study results (case reports and cross-sectional studies) on MetHb and COHb concentrations in the blood of COVID-19 patients. To this end, a systematic literature research was performed. For the case of MetHb, seven publications were identified (five case reports and two cross-sectional studies), and for the case of COHb, three studies were found (two cross-sectional studies and one case report). The findings reported in the publications show that an increase in MetHb and COHb can happen in COVID-19 patients, especially in critically ill ones, and that MetHb and COHb can increase to dangerously high levels during the course of the disease in some patients. -

Families and the Structural Relatedness Among Globular Proteins

DILL Department of Pharmaceutical Chemistry, University of California, San Francisco, California94143-1204 (RECEIVEDJanuary 6, 1993; REVISEDMANUSCRIPT RECEIVED February 18, 1993) Abstract Protein structures come in families. Are families “closely knit” or “loosely knit” entities? We describe a mea- sure of relatedness among polymer conformations. Based on weighted distance maps, this measure differs from existing measures mainly in two respects: (1) it is computationally fast, and (2) it can compare any two proteins, regardless of their relative chain lengths or degree of similarity. It does not require finding relative alignments. The measure is used here to determine the dissimilarities between all 12,403 possible pairs of 158 diverse protein structures from the Brookhaven Protein Data Bank (PDB). Combined with minimal spanning trees and hier- archical clustering methods,this measure is used to define structural families. It is also useful for rapidly searching a dataset of protein structures for specific substructural motifs.By using an analogy to distributions of Euclid- ean distances, we find that protein families are not tightly knit entities. Keywords: protein family; relatedness; structural comparison; substructure searches Pioneering work over the past 20 years has shown that positions after superposition. RMS is a useful distance proteins fall into families of related structures (Levitt & metric for comparingstructures that arenearly identical: Chothia, 1976; Richardson, 1981; Richardson & Richard- for example, when refining or comparing structures ob- son, 1989; Chothia & Finkelstein, 1990). -
Your Baby Has Hemoglobin E Or Hemoglobin O Trait for Parents
NEW HAMPSHIRE NEWBORN SCREENING PROGRAM Your Baby Has Hemoglobin E or Hemoglobin O Trait For Parents All infants born in New Hampshire are screened for a panel of conditions at birth. A small amount of blood was collected from your baby’s heel and sent to the laboratory for testing. One of the tests looked at the hemoglobin in your baby’s blood. Your baby’s test found that your baby has either hemoglobin E trait or hemoglobin O trait. The newborn screen- ing test cannot tell the difference between hemoglobin E and hemoglobin O so we do not know which one your baby has. Both hemoglobin E trait and hemoglobin O trait are common and do not cause health problems. Hemoglobin E trait and hemoglobin O trait will never develop to disease. What is hemoglobin? Hemoglobin is the part of the blood that carries oxygen to all parts of the body. There are different types of hemoglobin. The type of hemoglobin we have is determined from genes that we inherit from our parents. Genes are the instructions for how our body develops and functions. We have two copies of each gene; one copy is inherited from our mother in the egg and one copy is inherited from our father in the sperm. What are hemoglobin E trait and hemoglobin O trait? The normal, and most common, type of hemoglobin is called hemoglobin A. Hemoglobin E trait is when a baby inherited one gene for hemoglobin A from one parent and one gene for hemoglobin E from the other parent. -

Hemoglobin, Myoglobin and Neuroglobin in Endogenous Thiosulfate Production Processes

In these reactions, sulfite formed from thiosulfate is oxidized to sulfate while hydrogen sulfide is transformed into thiosulfate. These processes occurring mostly in mitochondria are described as a canonical hydrogen sulfide oxidation pathway. In this review, we discuss the current state of knowledge on the interactions between hydrogen sulfide and hemoglobin, myoglobin and neuroglobin and postulate that thiosulfate is a metabolically important product of this processes. Hydrogen sulfide oxidation by ferric hemoglobin, myoglobin and neuroglobin has been defined as a non-canonical hydrogen sulfide oxidation pathway. Until recently, it appeared that the goal of thiosulfate production was to delay irreversible oxidation of hydrogen sulfide to sulfate excreted in urine; while thiosulfate itself was only an intermediate, transient metabolite on the hydrogen sulfide oxidation pathway. In the light of data presented in this paper, it seems that thiosulfate is a molecule that plays a prominent role in the human body. Thus, we hope that all these findings will encourage further studies on the role of hemoproteins in the formation of this undoubtedly fascinating molecule and on the mechanisms responsible for its biological activity in the human body. -

Abbreviation: Lb, leghemoglobin. ABSTRACT Becana, M., Moran, J.F., Iturbe-Ormaetxe, I., Gogorcena, Y. and Escuredo, P.R. 1995. Structure and function of leghemoglobins. An. Estac. Exp. Aula Dei (Zaragoza) 21(3): 203-208. Leghemoglobin (Lb) is a myoglobin-like protein of about 16 kDa, which occurs in legume root nodules at very high concentra - tions. Usually the heme moiety is synthesized by the bacteroids but mitochondria may provide also heme for Lb when bacteria are defective in heme production or perhaps when Lb is produced in uninfected cells of nodules. Lb plays an essential role in the nitro - gen fixation process, by providing oxygen to the bacteroids at a low, but constant, concentration, which allows for simultaneous bac - teroid respiration and nitrogenase activity. Lb must be in the reduced, ferrous state to carry oxygen. Several factors within the nodu - les are conducive for Lb oxidation to its ferric, inactive form. During these inactivation reactions free radicals are generated. Howe - ver, healthy nodules contain around 80% of ferrous Lb and 20% of oxyferrous Lb, but not ferric Lb, which indicates that mechanisms exist in the nodules to maintain Lb reduced; these are the enzyme ferric Lb reductase and free flavins. Lb degradation is a largely unk - nown process, but several intermediates with modified hemes,presumably by oxidative attack,have been encountered, including modi - fied Lbam, choleglobin, and biliverdin.
