FunctionFunction unknown
ProductBiotinylated protein TB7.3
CommentsRv3221c, (MTCY07D11.05), len: 71 aa. TB7.3, Biotinylated protein (see citations below), equivalent (appears to have one additional residue) to Q9CCH9|ML0802|BTB7_MYCLE biotinylated protein TB7.3 homolog from Mycobacterium leprae (70 aa), FASTA scores: opt: 367, E(): 4e-18, (90.0% identity in 70 aa overlap); Q9XCD6|BTB7_MYCSM biotinylated protein TB7.3 homolog from Mycobacterium smegmatis (70 aa), FASTA scores: opt: 341, E(): 2.1e-16, (84.05% identity in 69 aa overlap). Similar to C-terminal part of various proteins e.g. Q9HPP8|ACC|VNG1532G biotin carboxylase from Halobacterium sp. strain NRC-1 (610 aa), FASTA scores: opt: 212, E(): 4e-07, (50.0% identity in 68 aa overlap); Q58628|PYCB_METJA|MJ1231 pyruvate carboxylase subunit B from Methanococcus jannaschii (567 aa), FASTA scores: opt: 192, E(): 7.8e-06, (44.8% identity in 58 aa overlap); Q9ZAA7|GCDC glutaconyl-CoA decarboxylase gamma subunit from Acidaminococcus fermentans (145 aa), FASTA scores: opt: 184, E(): 8.9e-06, (39.4% identity in 66 aa overlap); etc.
