Gene Rv1181
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 beta-ketoacyl synthase Pks4 |
| Comments | Rv1181, (MTV005.17), len: 1582 aa. Probable pks4, polyketide synthase, similar to many e.g. MCAS_MYCBO|Q02251 mycocerosic acid synthase from Mycobacterium bovis (2110 aa), FASTA scores: opt: 3518, E(): 0, (59.7% identity in 1614 aa overlap). Note that this similarity extends upstream of the first initiation codon into the upstream MTV005.16; the stop codon at the end of MTV005.16 is present in at least 4 independent clones (BAC, cosmid and pUC) from the genome (however an alternative nucleotide at position 1315191 (a->C; Stop489Y) has also been observed). The two CDS's may represent separate modules of the polyketide synthase. Rv1180/Rv1181 fusion has been called msl3. |
| Functional category | Lipid metabolism |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the cell wall and cell membrane fractions 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 M. tuberculosis H37Rv-infected guinea pig lungs at 30 and 90 days (See Kruh 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). |
| Transcriptomics | mRNA identified by microarray analysis and up-regulated after 4h of starvation (see citation below). |
| 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). M. tuberculosis H37Rv msl3|Rv1180/Rv1181 mutant aggregates in liquid culture and does not produce mycolipanoic, mycolipenic, or mycolipodienoic acids (See Dubey et al., 2002). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essentialgene by Himar1 transposon mutagenesis in CDC1551 strain (see Lamichhane et al., 2003).
