General annotation
FunctionInvolved in bioconversion of pimelate into dethiobiotin [catalytic activity: S-adenosyl-L-methionine + 8-amino-7- oxononanoate = S-adenosyl-4-methylthio-2-oxobutanoate + 7,8- diaminononanoate]. Supposedly involved in stationary-phase survival.
ProductAdenosylmethionine-8-amino-7-oxononanoate aminotransferase BioA
CommentsRv1568, (MTCY336.35c), len: 437 aa. bioA, adenosylmethionine-8-amino-7-oxononanoate aminotransferase , equivalent to a predicted homologous protein from Mycobacterium smegmatis (see citation below). Highly similar to BIOA_MYCLE|P4548 from Mycobacterium leprae (436 aa), FASTA results: opt: 2534, E(): 0, (85.1% identity in 436 aa overlap). Also similar to other Mycobacterium tuberculosis proteins e.g. MTCY227.12c (449 aa), FASTA score: E(): 3.5e-16, (29.5% identity in 421 aa overlap). Contains aminotransferases class-III pyridoxal-phosphate attachment site (PS00600). Belongs to class-III of pyridoxal-phosphate-dependent aminotransferases.
Functional categoryIntermediary metabolism and respiration
ProteomicsIdentified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011). Translational start site supported by proteomics data (See Kelkar et al., 2011).
MutantNon-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
