Axial Ligation and Redox Changes at the Cobalt Ion in Cobalamin Bound to Corrinoid Iron-Sulfur Protein (CoFeSP) or in Solution Characterized by XAS and DFT.

PLoS ONE, 2016
A cobalamin (Cbl) cofactor in corrinoid iron-sulfur protein (CoFeSP) is the primary methyl group donor and acceptor in biological carbon oxide conversion along the reductive acetyl-CoA pathway.

Evolutionary Trajectories of Methionine Metabolism in Mycobacterium and Its Application to Engineer a Vitamin B12 Whole‐Cell Ribosensor

Microbial Biotechnology, Volume 18, Issue 6, June 2025.
Molecular and functional experiments highlight the relevance of species‐specific polymorphisms in a B12 riboswitch of the Mycobacterium genus. This information provided proof‐of‐concept to engineer a whole‐cell biosensor capable of detecting vitamin B12. ABSTRACT Vitamin B12 metabolism differs among members of the Mycobacterium genus.

Lettuce fortification through vitamin B12‐producing bacteria – proof of concept study

Journal of the Science of Food and Agriculture, Volume 105, Issue 6, Page 3343-3354, April 2025.
Abstract BACKGROUND Vitamin B12 (cobalamin) can be produced de novo only by certain bacteria and archaea. It plays a crucial role in the health of animals and humans, which obtain it only through diet, mainly from animal products. This study aimed to identify endophytic bacterial strains capable of synthesizing vitamin B12 and enriching edible plants ...

Corrinoid-Metabolismus in Sporomusa ovata H1

, 2012
Sporomusa ovata H1 produces acetic acid from methanol plus CO2. Two vitamin B12 derivates are involved in this pathway: p-cresolylcobamide and phenolylcobamide.

Novel molecular markers for the detection of methanogens and phylogenetic analyses of methanogenic communities

Frontiers in Microbiology, 2015
Methanogenic Archaea produce approximately one billion tons of methane annually, but their biology remains largely unknown. This is partially due to the large phylogenetic and phenotypic diversity of this group of organisms, which inhabit various anoxic ...

Methanol and Carbon Monoxide Metabolism of the Thermophile Moorella caeni

Environmental Microbiology, Volume 27, Issue 4, April 2025.
An omics approach was used to elucidate the C1 metabolism of Moorella caeni DSM 21394 T, which exhibits acetogenic metabolism on methanol and hydrogenogenic metabolism on CO. Our results suggest that respiratory Complex I serves as the primary respiratory enzyme in methanol‐grown cells.

Comparative metagenomics of three Dehalococcoides-containing enrichment cultures: the role of the non-dechlorinating community

BMC Genomics, 2012
Background The Dehalococcoides are strictly anaerobic bacteria that gain metabolic energy via the oxidation of H2 coupled to the reduction of halogenated organic compounds. Dehalococcoides spp.
