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.

Comparative Analysis of Corrinoid Profiles across Host-Associated and Environmental Samples.
Biochemistry, 2022 Vitamin B12 (the cyanated form of cobalamin cofactors) is best known for its essential role in human health. In addition to its function in human metabolism, cobalamin also plays important roles in microbial metabolism and can impact microbial community ...

Molecular Microbiology, 2022 Some prokaryotes compartmentalize select metabolic capabilities. Salmonella enterica subspecies enterica serovar Typhimurium LT2 (hereafter S. Typhimurium) catabolizes ethanolamine (EA) within a proteinaceous compartment that we refer to as the ...

Four families of folate-independent methionine synthases.
PLoS Genetics, 2021 Although most organisms synthesize methionine from homocysteine and methyl folates, some have "core" methionine synthases that lack folate-binding domains and use other methyl donors.

Water Science and Technology, 2022 Complete dechlorination of trichloroethene (TCE) by Dehalococcoides mccartyi is catalyzed by reductive dehalogenases (RDases), which possess cobalamin as the crucial cofactor. However, virtually all D. mccartyi isolated thus far are corrinoid auxotrophs.

The 380 kb pCMU01 plasmid encodes chloromethane utilization genes and redundant genes for vitamin B12- and tetrahydrofolate-dependent chloromethane metabolism in Methylobacterium extorquens CM4: a proteomic and bioinformatics study. [PDF]
PLoS ONE, 2013 Chloromethane (CH3Cl) is the most abundant volatile halocarbon in the atmosphere and contributes to the destruction of stratospheric ozone. The only known pathway for bacterial chloromethane utilization (cmu) was characterized in Methylobacterium ...

Structure of a membrane-bound menaquinol:organohalide oxidoreductase
Nature Communications, 2023 Organohalide-respiring bacteria are key organisms for the bioremediation of soils and aquifers contaminated with halogenated organic compounds. The major players in this process are respiratory reductive dehalogenases, corrinoid enzymes that use ...

Scientific Reports, 2023 Despite the success of AlphaFold2 (AF2), it is unclear how AF2 models accommodate for ligand binding. Here, we start with a protein sequence from Acidimicrobiaceae TMED77 (T7RdhA) with potential for catalyzing the degradation of per- and polyfluoroalkyl ...

Nutrient cross-feeding in the microbial world. [PDF]
, 2014 The stability and function of a microbial community depends on nutritional interactions among community members such as the cross-feeding of essential small molecules synthesized by a subset of the population.
