Vitamin B12 as a source of variability in isotope effects for chloroform biotransformation by Dehalobacter [PDF]
MicrobiologyOpenCarbon and chlorine isotope effects for biotransformation of chloroform by different microbes show significant variability. Reductive dehalogenases (RDase) enzymes contain different cobamides, affecting substrate preferences, growth yields, and ...

Cobamide excretion allows Salmonella to transition from its anaerobic to aerobic lifestyle [PDF]
Microbiology SpectrumCobamides (Cbas) are structurally complex biomolecules used by cells of all domains of life. However, de novo Cba biosynthesis occurs only in some bacteria and archaea.

Understanding the sources, function, and irreplaceable role of cobamides in organohalide-respiring bacteria [PDF]
Frontiers in MicrobiologyHalogenated organic compounds are persistent pollutants that pose a serious threat to human health and the safety of ecosystems. Cobamides are essential cofactors for reductive dehalogenases (RDase) in organohalide-respiring bacteria (OHRB), which ...

Developing an E. coli heterologous expression system for characterizing a marine debrominase from Roseobacter sp. [PDF]
Applied and Environmental MicrobiologyReductive dehalogenases (RDases) are a family of enzymes that employ a cobamide cofactor and two iron-sulfur clusters to selectively cleave carbon-halogen bonds.

Characterization of Vitamin B12 Compounds in Fermented Poultry Manure Fertilizers
Agriculture, 2021 (1) Background: Currently, no data are available on the vitamin B12 content of an organic fertilizer product, viz. fermented poultry manure, or whether the organic fertilizer product contains vitamin B12 or inactive corrinoids (or both).
