Gene Rv0803
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in de novo purine biosynthesis (at the fourth step) [catalytic activity: ATP + 5'-phosphoribosylformylglycinamide + L-glutamine + H(2)O = ADP + phosphate + 5'-phosphoribosylformylglycinamidine + L-glutamate]. |
| Product | Phosphoribosylformylglycinamidine synthase II PurL (FGAM synthase II) |
| Comments | Rv0803, (MTCY07H7A.06c), len: 754 aa. PurL, phosphoribosylformylglycinamidine synthase II (see citations below), equivalent to NP_302451.1|NC_002677 phosphoribosylformylglycinamidine synthase II from Mycobacterium leprae (754 aa). Also highly similar to others e.g. Q9RKK5|PURL_STRCO from Streptomyces coelicolor (752 aa); P12042|PURL_BACSU from Bacillus subtilis (742 aa), FASTA score: (44.7% identity in 716 aa); etc. Start was chosen by similarity. Belongs to the FGAMS family. |
| Functional category | Intermediary metabolism and respiration |
| 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 membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011). |
| Mutant | 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).
