Corrinoids in anaerobic bacteria [PDF]
FEMS Microbiology Letters, 1990 C1-metabolizing bacteria were analyzed for their corrinoids. The autotrophic phototrophe Chloroflexus aurantiacus contains predominantly the light-sensitive coenzyme B12. The corrinoid could be teh prostethic group of a methylmalonyl-CoA mutase, which is involved in the CO2 fixing reaction sequence from proplonyl-CoA to succinyl CoA.

The inorganic chemistry of the cobalt corrinoids – an update
Journal of Inorganic Biochemistry, 2023The inorganic chemistry of the cobalt corrinoids, derivatives of vitamin B12, is reviewed, with particular emphasis on equilibrium constants for, and kinetics of, their axial ligand substitution reactions. The role the corrin ligand plays in controlling and modifying the properties of the metal ion is emphasised. Other aspects of the chemistry of these

A method for the efficient adenosylation of corrinoids
2022Adenosylcobamides (AdoCbas) are coenzymes required by organisms from all domains of life to perform challenging chemical reactions. AdoCbas are characterized by a cobalt-containing tetrapyrrole ring, where an adenosyl group is covalently attached to the cobalt ion via a unique Co-C organometallic bond.

Quantification of corrinoids in methanogenic bacteria
Current Microbiology, 1980Corrinoids in several diverse species of methanogens were quantified by a bioassay utilizingEscherichia coli 113-3, a corrinoid auxotroph. All five species examined contained >0.65 nmol corrinoid/mg dry cells when grown on H2/CO2 as carbon and energy source.

Analysis of corrinoids in ovine tissues
Biomedical Chromatography, 2005AbstractCorrinoids from various ovine tissue samples (liver, blood, small intestinal fluid and faeces) were analysed using a combination of high‐performance liquid chromatography (HPLC) and a radioisotope dilution assay (RIDA) to estimate the distribution of corrinoids—the cobalamins hydroxocobalamin (OH‐cbl), methylcobalamin (me‐cbl) and 5 ...
