Corrinoid (vitamin B12-like) cofactors contain various alpha-axial ligands, including 5,6-dimethylbenzimidazole (DMB) or adenine. The bacterium Salmonella enterica produces the corrin ring only under anaerobic conditions, but it can form "complete" corrinoids aerobically by importing an "incomplete" corrinoid, such as cobinamide

BluB is a distinct flavin destructase that catalyzes a complex oxygen-dependent conversion of reduced flavin mononucleotide (FMNH(2)) to form 5,6-dimethylbenzimidazole (DMB), the lower ligand of vitamin B(12). The catalyzed mechanism remains a challenge due to the discrepancy between the complexity

The vibrational spectra of 5,6-dimethyl benzimidazole (5,6DBZ) have been computed using the standard B3LYP/6-311G** method and basis set combinations. The solid phase FT-IR and FT-Raman spectra were recorded in the region 4000-400 and 3500-100 cm(-1), respectively. A close agreement was

Vitamin B12 (cobalamin) is among the largest known non-polymeric natural products, and the only vitamin synthesized exclusively by microorganisms. The biosynthesis of the lower ligand of vitamin B(12), 5,6-dimethylbenzimidazole (DMB), is poorly understood. Recently, we discovered that a Sinorhizobium meliloti
