General annotation
TypeCDS
FunctionInvolved in active transport of oligopeptide across the membrane (import). This protein is a component of the oligopeptide permease, a binding protein-dependent transport system; it binds peptides up to five amino acids long with high affinity.
ProductProbable periplasmic oligopeptide-binding lipoprotein OppA
CommentsRv1280c, (MTCY50.02), len: 591 aa. Probable oppA, oligopeptide-binding lipoprotein component of peptide transport system (see citation below), sharing some similarity to other periplasmic solute binding proteins e.g. OPPA_SALTY|P06202 periplasmic oligopeptide-binding protein from Salmonella typhimurium (542 aa), FASTA scores: E(): 5.1e-05, (22.1% identity in 458 aa overlap); etc. Also similar to Rv1166 and Rv2585c from Mycobacterium tuberculosis. Has possible N-terminal signal sequence and prokaryotic lipoprotein lipid attachment site (PS00013). Belongs to the bacterial extracellular solute-binding protein family 5.
Functional categoryCell wall and cell processes
ProteomicsIdentified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS; predicted integral membrane protein (See Xiong et al., 2005). Identified in the detergent phase of Triton X-114 extracts of M. tuberculosis H37Rv membranes using 1-DGE and MALDI-TOF-MS (See Sinha et al., 2005). Putative glycoprotein identified by LC/ESI-MS/MS in the culture filtrate of M. tuberculosis H37Rv (See Gonzalez-Zamorano et al., 2009). 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).
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). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
