FAD binding, cobinamide binding and active site communication in the corrin reductase (CobR) [PDF]

, 2014
Adenosylcobalamin, the coenzyme form of vitamin B12, is one Nature's most complex coenzyme whose de novo biogenesis proceeds along either an anaerobic or aerobic metabolic pathway. The aerobic synthesis involves reduction of the centrally chelated cobalt

Metagenomic Exploration Uncovers Several Novel ‘Candidatus’ Species Involved in Acetate Metabolism in High‐Ammonia Thermophilic Biogas Processes

Microbial Biotechnology, Volume 18, Issue 3, March 2025.
Metagenomic analysis of three thermophilic species was performed to identify key species for stable biogas production at high free ammonia levels (> 0.7 g/L). Potential acetogens and syntrophic acetate‐oxidising bacteria (SAOB) were recovered by looking for genes of the Wood–Ljungdahl pathway and glycine synthase reductase pathway.

Predicting the conformations of peptides and proteins in early evolution. A review article submitted to Biology Direct [PDF]

, 2008
Considering that short, mainly heterochiral, polypeptides with a high glycine content are expected to have played a prominent role in evolution at the earliest stage of life before nucleic acids were available, we review recent knowledge about ...

Unveiling the potentials and action mechanisms of Citri reticulatae Pericarpium as an anti‐inflammatory food

Food Frontiers, Volume 6, Issue 1, Page 163-184, January 2025.
The review summarized advances in utilizing CRP for the prevention and treatment of inflammation under various pathological conditions. The underlying mechanism has focused on polymethoxyflavones (PMFs) present in CRP and its interaction with gut microbiota. Abstract Modern lifestyle has led human body under a frequent exposure of chronic inflammation.

Isolation and characterization of a novel methanogen Methanosarcina hadiensis sp. nov. from subsurface Boom Clay pore water

Environmental Microbiology, Volume 26, Issue 12, December 2024.
We isolated a novel methanogenic archaeon, Methanosarcina hadiensis sp. nov. (TD41E1‐1), from Boom Clay pore water at a depth of 225 m. It exhibits unique characteristics compared to previously characterized Methanosarcina species, such as the inability to perform acetoclastic methanogenesis and the presence of extensive surface appendages.
