Gene Rv1296
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Threonine biosynthesis from asparate (fourth step) [catalytic activity: ATP + L-homoserine = ADP + O-phospho-L-homoserine]. |
| Product | Probable homoserine kinase ThrB |
| Comments | Rv1296, (MTCY373.16), len: 316 aa. Probable thrB, homoserine kinase (see citation below), highly similar to KHSE_MYCLE|P45836 from Mycobacterium leprae (314 aa), FASTA scores, opt: 1657, E(): 0, (82.0% identity in 311 aa overlap). Contains PS00639 Eukaryotic thiol (cysteine) proteases histidine active site, and PS00627 GHMP kinases putative ATP-binding domain. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza 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).
