Biosynthesis of Nitrogenase Cofactors

open access: yesChemical Reviews, 2020
Nitrogenase harbors three distinct metal prosthetic groups that are required for its activity. The simplest one is a [4Fe-4S] cluster located at the Fe protein nitrogenase component.

Coordinated Slowing of Metabolism in Enteric Bacteria under Nitrogen Limitation: A Perspective [PDF]

open access: yesarXiv, 2001
It is natural to ask how bacteria coordinate metabolism when depletion of an essential nutrient limits their growth, and they must slow their entire rate of biosynthesis. A major nutrient with a fluctuating abundance is nitrogen. The growth rate of enteric bacteria under nitrogen-limiting conditions is known to correlate with the internal concentration

A translation proofreader of archaeal origin imparts multi-aldehyde stress tolerance to land plants

open access: yeseLife
Aldehydes, being an integral part of carbon metabolism, energy generation, and signalling pathways, are ingrained in plant physiology. Land plants have developed intricate metabolic pathways which involve production of reactive aldehydes and its ...

Proline biosynthesis is a vent for TGFβ‐induced mitochondrial redox stress

open access: yesEMBO Journal, 2020
The production and secretion of matrix proteins upon stimulation of fibroblasts by transforming growth factor‐beta (TGFβ) play a critical role in wound healing.

On the Origin of Protein Biosynthesis

open access: yesZeitschrift für Naturforschung C, 1975
Abstract There is a very close steric relationship between the codon-anticodon site which accounts for the genetic code dictionary and a polynucleotide replicase site. Protein biosynthesis must therefore have arisen out of a primaeval polynucleotide replicase system.

Why is life so exact? [PDF]

open access: yesarXiv, 2010
This is my attempt to answer Schr\"odinger's question: "What is Life?". In living cell the local combination of atoms is reproduced with incredible accuracy. In the case of protein biosynthesis the notion of the physical aspect of the process can be qualitatively enriched by taking into account the symmetry of conformational oscillations.

Evolution of the genetic code. Why are there strong and weak letter doublets? The first gene, the first protein. Early (ancient) biosynthesis of protein [PDF]

open access: yesarXiv, 2008
The idea of the evolution of the genetic code from the CG to the CGUA alphabet has been developed further. The assumption of the originally triplet structure of the genetic code has been substantiated. The hypothesis of the emergence of stop codons at the early stage of the evolution of the genetic code has been additionally supported. The existence of

RNA-seq analysis of Brachypodium distachyon responses to Barley stripe mosaic virus infection

open access: yesCrop Journal, 2017
Barley stripe mosaic virus (BSMV) is the type member of the genus Hordeivirus. Brachypodium distachyon line Bd3-1 shows resistance to the BSMV ND18 strain, but is susceptible to an ND18 double mutant (β NDTGB1R390K, T392K) in which lysine is substituted ...

A secreted Ustilago maydis effector promotes virulence by targeting anthocyanin biosynthesis in maize

open access: yeseLife, 2014
The biotrophic fungus Ustilago maydis causes smut disease in maize with characteristic tumor formation and anthocyanin induction. Here, we show that anthocyanin biosynthesis is induced by the virulence promoting secreted effector protein Tin2.

Altered proteome in translation initiation fidelity defective eIF5G31R mutant causes oxidative stress and DNA damage

open access: yesScientific Reports, 2022
The recognition of the AUG start codon and selection of an open reading frame (ORF) is fundamental to protein biosynthesis. Defect in the fidelity of start codon selection adversely affect proteome and have a pleiotropic effect on cellular function ...
