Gene Rv2946c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Polyketide synthase possibly involved in lipid synthesis |
| Product | Probable polyketide synthase Pks1 |
| Comments | Rv2946c, (MTCY24G1.03), len: 1616 aa. Probable pks1, polyketide synthase, similar to many e.g. ML035|AL583917|Q9CD81 putative polyketide synthase from Mycobacterium leprae (2103 aa), Fasta scores: opt: 8761, E(): 0, (82.6% identity in 1620 aa overlap); etc. Almost identical in part to G560507|Q50470 PKS002C protein from Mycobacterium tuberculosis (fragment) (950 aa), Fasta scores: opt: 5685, E(): 0, (95.3% identity in 927 aa overlap). Also similar to Mycobacterium tuberculosis polyketide synthases pks7|Rv1661|P94996 (2126 aa) (54.6% identity in 1632 aa); pks12|Rv2048c|O53490 (4151 aa) (58.0% identity in 1606 aa); pks8|rv1662|O65933 (1602 aa) (59.7% identity in 1144 aa). Contains a PS00012 Phosphopantetheine attachment site. Note pks1 has been shown to be involved in the biosynthesis of phthiocerol. pks15/pks1 has been shown to be involved in the biosynthesis of phenolphthiocerol glycolipids. |
| Functional category | Lipid metabolism |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). |
| Mutant | Non-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019).
