General annotation
FunctionInvolved in cobalamin biosynthesis; transforms cobyrinic acid into cobinamide [catalytic activity: ATP + cob(I)alamin + H(2)O = orthophosphate + pyrophosphate + adenosylcobalamin].
ProductProbable cob(I)alamin adenosyltransferase CobO (corrinoid adenosyltransferase) (corrinoid adotransferase activity)
CommentsRv2849c, (MTCY24A1.08), len: 207 aa. Probable cobO, cob(I)alamin adenosyltransferase, highly similar to Q9RJ17|COBO from Streptomyces coelicolor (199 aa), FASTA scores: opt: 918, E(): 1.1e-55, (64.75% identity in 207 aa overlap); and similar to others e.g. O30785|COBO from Rhodobacter capsulatus (Rhodopseudomonas capsulata) (212 aa), FASTA scores: opt: 329, E(): 2.8e-15, (44.3% identity in 185 aa overlap); P29930|COBO_PSEDE from Pseudomonas denitrificans (213 aa), FASTA scores: opt: 280, E(): 6.5e-12, (38.9% identity in 185 aa overlap); P31570|BTUR_SALTY|COBA from Salmonella typhimurium (196 aa), FASTA scores: opt: 278, E(): 8.4e-12, (39.8% identity in 196 aa overlap); etc. Cofactor: manganese. Note that previously known as cobA.
