General annotation
Gene nameamiB2
Rv numberRv1263
FunctionInvolved in cellular metabolism, active on 2- to 6- carbon aliphatic amides and on many aromatic amides [catalytic activity: a monocarboxylic acid amide + H(2)O = a monocarboxylate + NH(3)].
ProductProbable amidase AmiB2 (aminohydrolase)
CommentsRv1263, (MTCY50.19c), len: 462 aa. Probable amiB2, amidase. Similar to G1001278 hypothetical 54.3 kDa protein (506 aa), FASTA scores: opt: 767, E(): 7.6e-40, (32.8% identity in 461 aa overlap), also similar to G580673 rhodococcus enantiose lective amidase gene (462 aa), FASTA scores, opt: 668, E(): 7.4e-34, (33.5% identity in 484 aa overlap) also to NYLA_PSES8|P13398 6-aminohexanoate-cyclic-dimer hydrolase (492 aa), FASTA scores opt: 543, E(): 3.1e-26, (33.5% identity in 493 aa overlap). Also similar to MTCY274.19c (33.5% identity in 427 aa overlap). Similar to other putative amidases in M. tuberculosis; Rv2363, Rv2888c, etc. Contains PS00017 ATP/GTP-binding site motif A. Belongs to the amidase family.

ProteomicsIdentified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS (See Xiong et al., 2005). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011). Translational start site supported by proteomics data (See de Souza et al., 2011) (See Kelkar et al., 2011).
Mutationnon essential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website
