Gene Rv0050
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in peptidoglycan synthesis (at the final stages), cell wall formation. Synthesis of cross-linked peptidoglycan from the lipid intermediates. The enzyme has a penicillin-insensitive transglycosylase N-terminal domain (formation of linear glycan strands) and a penicillin-sensitive transpeptidase C-terminal domain (cross-linking of the peptide subunits). |
| Product | Probable bifunctional penicillin-binding protein 1A/1B PonA1 (murein polymerase) (PBP1): penicillin-insensitive transglycosylase (peptidoglycan TGASE) + penicillin-sensitive transpeptidase (DD-transpeptidase) |
| Comments | Rv0050, (MTCY21D4.13), len: 678 aa. Probable ponA1, penicillin-binding protein (class A), bienzymatic protein with transglycosylase and transpeptidase activities (see Graham & Clark-Curtiss 1999), highly similar to many (see Billman-Jacobe et al., 1999). Belongs to the transglycosylase family in the N-terminal section, and to the transpeptidase family in the C-terminal section. |
| 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). |
| Transcriptomics | mRNA identified by SCOTS method, 48h and 110h after infection of cultured human primary macrophages (see Graham & Clark-Curtiss 1999). DNA microarrays detect expression in M. tuberculosis H37Rv in vivo (in BALB/c and SCID mice) but not in vitro (in 7H9 medium) (See Talaat et al., 2004). RT-PCR shows increased expression in M. tuberculosis H37Rv grown in anaerobic non-replicating conditions (See Saxena et al., 2008). |
| Mutant | 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 strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
