FunctionRemoves the amino-terminal methionine from nascent proteins [catalytic activity: L-methionylpeptide + H2O = L-methionine + peptide].
ProductMethionine aminopeptidase MapA (map) (peptidase M) (MetAP)
CommentsRv0734, (MTV041.08), len: 266 aa. mapA, methionine aminopeptidase (map), equivalent to Z98756|MLCB2492_29 probable methionine aminopeptidase from Mycobacterium leprae (266 aa), FASTA scores: opt: 1717, E(): 0, (83.4% identity in 265 aa overlap). Also highly similar to many e.g. T35553 methionine aminopeptidase from Streptomyces coelicolor (278 aa); etc. Also similar to Rv2861c|MAPB probable methionine aminopeptidase from Mycobacterium tuberculosis (285 aa). Belongs to peptidase family M24A; also known as the map family 1. Cofactor: cobalt; binds 2 ions per subunit. Conserved in M. tuberculosis, M. leprae, M. bovis and M. avium paratuberculosis; predicted to be essential for in vivo survival and pathogenicity (See Ribeiro-Guimaraes and Pessolani, 2007).
Functional categoryIntermediary metabolism and respiration
ProteomicsIdentified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). 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; enriched in the membrane fraction and predicted N-terminal signal peptide is uncleaved (See de Souza et al., 2011).
MutantNon-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
