Namely, Aspartokinase and Aspartate 3-Semialdehyde Dehydrogenase) Are Not Subject to Feedback Inhibition Control by the End Product Methionine
REGULATION OF HOMOSERINE BIOSYNTHESIS BY L-CYSTEINE, A TERMINA L METABOLITE OF A LINKED PA THWA Y* By PRASANTA DATTA DEPARTMENT OF BIOLOGICAL CHEMISTRY, UNIVERSITY OF MICHIGAN, ANN ARBOR Communicated by Martin D. Kamen, June 23, 1967 In bacteria, the amino acid homoserine is a key branch-point intermediate in the synthesis of several amino acids of the aspartic pathway.' On the one hand, homoserine is converted to threonine (and thus to isoleucine), and through a separate sequence of reactions is transformed to methionine.1 In the latter se- quence, a succinylated product of homoserine is condensed with cysteine to pro- duce cystathionine,2-5 a precursor of methionine. Recent studies (see refs. 6 and 7 for up-to-date reviews on the subject) with several microorganisms have revealed that the synthesis of homoserine is regulated by various combinations of repression and/or feedback inhibition controls of early biosynthetic enzymes of the aspartic pathway by several end-product metabolites. One of these enzymes, homoserine dehydrogenase, catalyzes the pyridine nucleotide-linked reduction of aspartate j3-semialdehyde to homoserine. In the various bacteria that have been examined, this dehydrogenase as well as the two earlier enzymes of the path- way (namely, aspartokinase and aspartate 3-semialdehyde dehydrogenase) are not subject to feedback inhibition control by the end product methionine. This report describes the results of experiments on the control of activity of several bacterial homoserine dehydrogenases by L-cysteine, a terminal metabolite of a linked or connecting pathway, required for the synthesis of cystathionine.2-5 The findings suggest that the size of the homoserine pool in bacterial cells must depend, at least in part, on complex interdependent regulatory interactions of both cysteine and threonine on homoserine dehydrogenase. -

Endophytic Fungi: Treasure for Anti-Cancerous Compounds
International Journal of Pharmacy and Pharmaceutical Sciences ISSN- 0975-1491 Vol 8, Issue 8, 2016 Review Article ENDOPHYTIC FUNGI: TREASURE FOR ANTI-CANCEROUS COMPOUNDS ANAND DILIP FIRODIYAa*, RAJESH KUMAR TENGURIAb aCSRD, Peoples University, Bhopal 462037, Madhya Pradesh, India, bDepartment of Botany, Govt. PG College, Rajgarh 496551, Madhya Pradesh, India Email: [email protected] Received: 22 Apr 2016 Revised and Accepted: 20 June 2016 ABSTRACT Endophytic fungi that live asymptomatically inside the plant tissues have novel bioactive metabolites exhibiting a variety of biological activities, especially against cancer. This review highlights the research progress on the production of anticancer compounds by endophytic fungi from 1990- 2015. Anticancer activity is generally associated with the cytotoxicity of the compounds present in the endophytic fungi. The ubiquitous nature of endophytic fungi synthesise diverse chemicals with promising anticancer activity from either their original host or related species. Modification in fermentation parameters and genetic insight of endophytes may produce novel anti-cancerous compounds. Keywords: Cancer, Medicinal plants, Secondary metabolites © 2016 The Authors.

Supplemental Methods
Supplemental Methods: Sample Collection Duplicate surface samples were collected from the Amazon River plume aboard the R/V Knorr in June 2010 (4 52.71’N, 51 21.59’W) during a period of high river discharge. The collection site (Station 10, 4° 52.71’N, 51° 21.59’W; S = 21.0; T = 29.6°C), located ~ 500 Km to the north of the Amazon River mouth, was characterized by the presence of coastal diatoms in the top 8 m of the water column. Sampling was conducted between 0700 and 0900 local time by gently impeller pumping (modified Rule 1800 submersible sump pump) surface water through 10 m of tygon tubing (3 cm) to the ship's deck where it then flowed through a 156 µm mesh into 20 L carboys. In the lab, cells were partitioned into two size fractions by sequential filtration (using a Masterflex peristaltic pump) of the pre-filtered seawater through a 2.0 µm pore-size, 142 mm diameter polycarbonate (PCTE) membrane filter (Sterlitech Corporation, Kent, CWA) and a 0.22 µm pore-size, 142 mm diameter Supor membrane filter (Pall, Port Washington, NY). Metagenomic and non-selective metatranscriptomic analyses were conducted on both pore-size filters; poly(A)-selected (eukaryote-dominated) metatranscriptomic analyses were conducted only on the larger pore-size filter (2.0 µm pore-size). All filters were immediately submerged in RNAlater (Applied Biosystems, Austin, TX) in sterile 50 mL conical tubes, incubated at room temperature overnight and then stored at -80oC until extraction. Filtration and stabilization of each sample was completed within 30 min of water collection. -

Abstract: Fungal endophytes are well-established sources of biologically active natural compounds with many producing pharmacologically valuable specific plant-derived products. This review details typical plant-derived medicinal compounds of several classes, including alkaloids, coumarins, flavonoids, glycosides, lignans, phenylpropanoids, quinones, saponins, terpenoids, and xanthones that are produced by endophytic fungi. This review covers the studies carried out since the first report of taxol biosynthesis by endophytic Taxomyces andreanae in 1993 up to mid-2020. The article also highlights the prospects of endophyte-dependent biosynthesis of such plant-derived pharma- cologically active compounds and the bottlenecks in the commercialization of this novel approach Citation: Singh, A.; Singh, D.K.; Kharwar, R.N.; White, J.F.; Gond, S.K. in the area of drug discovery. After recent updates in the field of ‘omics’ and ‘one strain many Fungal Endophytes as Efficient compounds’ (OSMAC) approach, fungal endophytes have emerged as strong unconventional source Sources of Plant-Derived Bioactive of such prized products. -

In nitrogen-fixing and nodulating alpha-rhizobia, homocitrate is usually provided to bacteroids in root nodules by their plant host. In contrast, non-nodulating free-living diazotrophs encode the homocitrate synthase (NifV) and reduce N2 in nitrogen-limiting free-living conditions. Paraburkholderia phymatum STM815 is a beta-rhizobial strain, which can enter symbiosis with a broad range of legumes, including Citation: Bellés-Sancho, P.; Lardi, M.; papilionoids and mimosoids. In contrast to most alpha-rhizobia, which lack nifV, P. phymatum Liu, Y.; Hug, S.; Pinto-Carbó, M.A.; harbors a copy of nifV on its symbiotic plasmid. We show here that P. phymatum nifV is essential for Zamboni, N.; Pessi, G. -
