A 4-fold purification has been reached with a 1.3 % recovery. The subunit molecular weight of adenosine nucleosidase was determined by mass spectrometry to be 26,103 daltons. The number of subunits was 1. The Michaelis constant, Km, and the maximum velocity, V max, for adenosine were determined to be 137 ± 48 µM, and 0.34 ± 0.02 µM/min respectively.

ABSTRACT Exodeoxyribonuclease III (EXOIII) acts as a 3’→5’ exonuclease and is homologous to purinic/apyrimidinic (AP) en- donuclease (APE), which plays an important role in the base excision repair pathway. To structurally investigate the reaction and substrate recognition mechanisms of EXOIII, a crystallographic study of EXOIII from Sulfolobus tokodaii strain 7 was carried out. The purified enzyme was crystallized by using the hanging-drop vapor-diffusion method. The crystals belonged to space group C2, with unit-cell parameters a = 154.2, b = 47.7, c = 92.4 Å, β = 125.8˚ and diffracted to 1.5 Å resolution.

The Classification of Esterases: an Important Gene Family Involved in Insecticide Resistance - a Review
Mem Inst Oswaldo Cruz, Rio de Janeiro, Vol. 107(4): 437-449, June 2012 437 The classification of esterases: an important gene family involved in insecticide resistance - A Review Isabela Reis Montella1,2, Renata Schama1,2,3/+, Denise Valle1,2,3 1Laboratório de Fisiologia e Controle de Artrópodes Vetores, Instituto Oswaldo Cruz-Fiocruz, Av. Brasil 4365, 21040-900 Rio de Janeiro, RJ, Brasil 2Instituto de Biologia do Exército, Rio de Janeiro, RJ, Brasil 3Instituto Nacional de Ciência e Tecnologia em Entomologia Molecular, Rio de Janeiro, RJ, Brasil The use of chemical insecticides continues to play a major role in the control of disease vector populations, which is leading to the global dissemination of insecticide resistance. A greater capacity to detoxify insecticides, due to an increase in the expression or activity of three major enzyme families, also known as metabolic resistance, is one major resistance mechanisms. The esterase family of enzymes hydrolyse ester bonds, which are present in a wide range of insecticides; therefore, these enzymes may be involved in resistance to the main chemicals employed in control programs. Historically, insecticide resistance has driven research on insect esterases and schemes for their classification. Currently, several different nomenclatures are used to describe the esterases of distinct species and a universal standard classification does not exist. The esterase gene family appears to be rapidly evolving and each insect species has a unique complement of detoxification genes with only a few orthologues across species. The examples listed in this review cover different aspects of their biochemical nature. However, they do not appear to contribute to reliably distinguish among the different resistance mechanisms.

Niiranen , MD, PhD BACKGROUND: Several small-scale animal studies have suggested that gut microbiota and blood pressure (BP) are linked. However, results from human studies remain scarce and conflicting. We wanted to elucidate the multivariable-adjusted as- sociation between gut metagenome and BP in a large, representative, well-phenotyped population sample. We performed a focused analysis to examine the previously reported inverse associations between sodium intake and Lactobacillus abun- dance and between Lactobacillus abundance and BP. METHODS AND RESULTS: We studied a population sample of 6953 Finns aged 25 to 74 years (mean age, 49.2±12.9 years; 54.9% women). The participants underwent a health examination, which included BP measurement, stool collection, and 24-hour urine sampling (N=829). Gut microbiota was analyzed using shallow shotgun metagenome sequencing. In age- and sex-adjusted models, the α (within-sample) and β (between-sample) diversities of taxonomic composition were strongly re- lated to BP indexes (P<0.001 for most). In multivariable-adjusted models, β diversity was only associated with diastolic BP (P=0.032).

ASPA Gene Aspartoacylase
ASPA gene aspartoacylase Normal Function The ASPA gene provides instructions for making an enzyme called aspartoacylase. In the brain, this enzyme breaks down a compound called N-acetyl-L-aspartic acid (NAA) into aspartic acid (an amino acid that is a building block of many proteins) and another molecule called acetic acid. The production and breakdown of NAA appears to be critical for maintaining the brain's white matter, which consists of nerve fibers surrounded by a myelin sheath. The myelin sheath is the covering that protects nerve fibers and promotes the efficient transmission of nerve impulses. The precise function of NAA is unclear. Researchers had suspected that it played a role in the production of the myelin sheath, but recent studies suggest that NAA does not have this function. The enzyme may instead be involved in the transport of water molecules out of nerve cells (neurons). Health Conditions Related to Genetic Changes Canavan disease More than 80 mutations in the ASPA gene are known to cause Canavan disease, which is a rare inherited disorder that affects brain development. Researchers have described two major forms of this condition: neonatal/infantile Canavan disease, which is the most common and most severe form, and mild/juvenile Canavan disease. The ASPA gene mutations that cause the neonatal/infantile form severely impair the activity of aspartoacylase, preventing the breakdown of NAA and allowing this substance to build up to high levels in the brain. The mutations that cause the mild/juvenile form have milder effects on the enzyme's activity, leading to less accumulation of NAA.

Pyrimidine Base Degradation in Cultured Murine C-1300 Neuroblastoma Cells and in Situ Tumors
Pyrimidine base degradation in cultured murine C-1300 neuroblastoma cells and in situ tumors. M Tuchman, … , M L Ramnaraine, B L Mirkin J Clin Invest. 1988;81(2):425-430. https://doi.org/10.1172/JCI113336. Research Article Dihydropyrimidine dehydrogenase (DPD), the initial, rate-limiting step in pyrimidine degradation, was studied in two cell lines of murine neuroblastoma (MNB-T1 and MNB-T2) that were derived from C-1300 MNB tumor carried in A/J mice. The MNB-T2 (low malignancy) cell line was originally derived from the in situ tumor and carried in tissue culture for more than 100 passages; the MNB-T1 (high malignancy) line consisted of a new sub-culture that was also established from the in situ MNB tumor. DPD activity was determined in cytosolic preparations of MNB utilizing high performance liquid chromatography to separate the radiolabeled substrate ([2-14C]thymine) from [2-14C]dihydrothymine. The apparent affinity of DPD for NADPH in MNB cells (Km approximately 0.08 mM) was identical to that of A/J mouse brain and liver. The DPD activity of the high malignancy (MNB-T1) cell line was 14.3% of that observed in the low malignancy (MNB-T2) line. In situ tumors formed after implantation of high malignancy (MNB-T1) cells into A/J mice had only 25.2% of the DPD activity observed in tumors derived from low malignancy (MNB-T2) cells. When MNB-T2 cells were injected into naive A/J mice, tumors developed in only 68% of animals, the tumor growth rate was slow and a mortality of 20% was observed.
