cobA function is required for both de novo cobalamin biosynthesis and assimilation of exogenous corrinoids in Salmonella typhimurium.

Journal of bacteriology - 1 Jan 1990

Escalante-Semerena J C, Suh S J, Roth J R

Abstract excerpt

Salmonella typhimurium is able to synthesize cobalamin (B12) under anaerobic growth conditions. The previously described cobalamin biosynthetic mutations (phenotypic classes CobI, CobII, and CobIII) map in three operons located near the his locus (minute 41). A new class of mutant (CobIV) defective in B12 biosynthesis was isolated and characterized. These mutations map between the cysB and trp loci (minute 34)...
