Gene Rv2467 (pepD)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Aminopeptidase with broad substrate specificity to several peptides (could preferentially cleave leucine, arginine and lysine in peptide-bond-containing substrates). |
| Product | Probable aminopeptidase N PepN (Lysyl aminopeptidase) (LYS-AP) (alanine aminopeptidase) |
| Comments | Rv2467, (MTV008.23), len: 861 aa. Probable pepN, aminopeptidase N, equivalent to Q9CBX9|ML1486 probable aminopeptidase from Mycobacterium leprae (862 aa), FASTA scores: opt: 4751,E(): 0, (83.3% identity in 862 aa overlap). Also highly similar to others e.g. Q11010|AMPN_STRLI|PEPN from Streptomyces lividans (857 aa), FASTA scores: opt: 2839, E(): 1.8e-170, (53.25% identity in 864 aa overlap); Q9L1Z2|PEPN from Streptomyces coelicolor (857 aa), FASTA scores: opt: 2834, E(): 3.8e-170, (53.1% identity in 864 aa overlap); P37896|AMPN_LACDL|PEPN from Lactobacillus delbrueckii (subsp. lactis) (842 aa), FASTA scores: opt: 719, E(): 2.4e-37, (31.65% identity in 439 aa overlap); etc. Contains PS00142 Neutral zinc metallopeptidases, zinc-binding region signature. Belongs to peptidase family M1 (zinc metalloprotease), also known as the PEPN subfamily. Note that previously known as pepD. 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 category | Intermediary metabolism and respiration |
| Proteomics | Identified 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 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). |
| Mutant | Non-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 by Himar1 transposon mutagenesis in H37Rv and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Non essential gene for growth in vitro by Tn5370 transposon mutagenesis of H37Rv strain but mutant is more virulent in SCID mice (see McAdam et al., 2002).
