Gene Rv0127
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Catalyzes the transfer of a phosphate group from ATP to maltose to produce maltose-1-phosphate [catalytic activity: ATP + maltose = ADP + maltose-1-phosphate] |
| Product | Maltokinase Mak |
| Comments | Rv0127, (MTCI418B.09, MTCI5.01), len: 455 aa. Mak, maltokinase; highly similar to various proteins e.g. AJ0012|SCJ001205_4 hypothetical protein from Streptomyces coelicolor A3(2) (464 aa), FASTA scores: opt: 412, E(): 1.1e-19, (40.6% identity in 485 aa overlap); AJ0012|SCJ001206_5 hypothetical protein from Streptomyces coelicolor A3(2) (453 aa), FASTA scores: opt: 403, E(): 4.3 e-19, (36.5% identity in 455 aa overlap). |
| Functional category | Virulence, detoxification, adaptation |
| 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 cytosol 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 the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011). |
| Mutant | 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).
