Gene Rv1092c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Coenzyme A (CoA) biosynthesis [catalytic activity: ATP + pantothenate = ADP + D-4'- phosphopantothenate.] |
| Product | Probable pantothenate kinase CoaA (pantothenic acid kinase) |
| Comments | Rv1092c, (MTV017.45c), len: 312 aa. Probable coaA, pantothenate kinase, similar to many e.g. P15044|COAA_ECOLI Escherichia coli (316 aa), FASTA scores :opt: 1079, E(): 0, (52.7% identity in 311 aa overlap). Equivalent to AL049491|MLCB1222_17 Mycobacterium leprae (312 aa) (93.6% identity in 312 aa overlap). Contains PS00017 ATP/GTP-binding site motif A (P-loop). Belongs to the pantothenate kinase family. |
| Functional category | Intermediary metabolism and respiration |
| 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 membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS (See Xiong et al., 2005). 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). |
| Transcriptomics | mRNA identified by microarray analysis and down-regulated after 96h of starvation (see citation below). |
| 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). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
