Gene Rv1663
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Potentially involved in some intermediate steps for the synthesis of a polyketide molecule which may be involved in secondary metabolism |
| Product | Probable polyketide synthase Pks17 |
| Comments | Rv1663, (MTCY275.02), len: 502 aa. Probable pks17, polyketide synthase, similar to other polyketide synthases e g. ERY2_SACER|Q03132 erythronolide synthase, modules 3 and 4 (3567 aa) from Saccharopolyspora erythraea (Streptomyces erythraeus), FASTA scores: opt: 1207, E(): 0, (43.9% identity in 531 aa overlap). Also similar to other Mycobacterium tuberculosis probable polyketide synthases e.g. pks7 and pks1. Note that the similarity extends into the upstream ORF Rv1662 (MTCY275.01) and this could be accounted for by a frameshift, although the sequence has been checked and no discrepancy was found. Contains PS00012 Phosphopantetheine attachment site. |
| Functional category | Lipid metabolism |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). |
| Mutant | Non-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). 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).
