Gene Rv3666c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Thought to be involved in active transport of dipeptide across the membrane (import). |
| Product | Probable periplasmic dipeptide-binding lipoprotein DppA |
| Comments | Rv3666c, (MTV025.014c), len: 541 aa. Probable dppA, dipeptide-binding lipoprotein component of dipeptide transport system (see citation below), similar to many substrate-binding proteins e.g. Q9F353|SC9E12.02 putative peptide transport system secreted peptide-binding protein from Streptomyces coelicolor (544 aa), FASTA scores: opt: 1200, E(): 9e-67, (39.2% identity in 538 aa overlap); P24141|OPPA_BACSU oligopeptide-binding protein from Bacillus subtilis (545 aa), FASTA scores: opt: 523, E(): 7.9e-25, (26.15% identity in 516 aa overlap); P23843|OPPA_ECOLI periplasmic oligopeptide-binding protein from Escherichia coli (543 aa), FASTA scores: opt: 452, E(): 2e-20, (25.9% identity in 529 aa overlap); etc. Contains probable N-terminal signal sequence. |
| Functional category | Cell wall and cell processes |
| Proteomics | 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). |
| 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). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Check for mutants available at TARGET website |
