Gene Rv0505c (serB)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Removes a phosphate from phosphoserine [catalytic activity: phosphoserine + H2O = serine + phosphate]. |
| Product | Possible phosphoserine phosphatase SerB1 (PSP) (O-phosphoserine phosphohydrolase) (pspase) |
| Comments | Rv0505c, (MTCY20G9.32c), len: 373 aa. Possible serB1, phosphoserine phosphatase, equivalent (but longer ~70 aa in N-terminus) to S72914|serB phosphoserine phosphatase from Mycobacterium leprae (300 aa), FASTA scores: opt: 1570, E(): 0, (83.0% identity in 306 aa overlap). C-terminus highly similar to CAB55344.1|AJ010584 phosphoserine phosphatase from Streptomyces coelicolor (266 aa). Low similarity to SERB_ECOLI|P06862 phosphoserine phosphatase from Escherichia coli strains K12 and O157:H7 (322 aa), FASTA scores: opt: 148, E(): 0.043, (24.0% identity in 150 aa overlap). C-terminus is also similar to O33611|AB004855_1|IMD_STRCN protein involved in inhibition of morphological differentiation from Streptomyces cyaneus (277 aa), FASTA score: (37.7% identity in 252 aa overlap). Seems to belong to the SERB family. Note that previously known as serB. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS; predicted transmembrane protein (See Gu et al., 2003). Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS; predicted integral membrane protein (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). |
| 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). Non 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). Check for mutants available at TARGET website |
