Gene Rv1293
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in biosynthesis of lysine (last step) [catalytic activity: MESO-2,6-diaminoheptanedioate = L-lysine + CO(2)]. |
| Product | Diaminopimelate decarboxylase LysA (DAP decarboxylase) |
| Comments | Rv1293, (MTCY373.13), len: 447 aa. lysA, diaminopimelate decarboxylase (see citation below), almost identical to DCDA_MYCTU|P31848. Contains PS00878 Orn/DAP/Arg decarboxylases family 2 pyridoxal-P attachment site, PS00879 Orn/DAP/Arg decarboxylases family 2 signature 2. Belongs to family 2 of ornithine, DAP, and arginine decarboxylases. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the cell wall fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). 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). Translational start site supported by proteomics data (See de Souza et al., 2011) (See Kelkar et al., 2011). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). 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). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
