FunctionGenerates CO(2) and H(2)O from H(2)co(3), and possibly involved in transport of sulfate across the membrane.
ProductProbable transmembrane carbonic anhydrase (carbonate dehydratase) (carbonic dehydratase)
CommentsRv3273, (MTCY71.13), len: 764 aa. Probable transmembrane protein (N-terminal part is hydrophobic) with probable carbonic anhydrase activity (in C-terminal part). Possibly involved in transport of sulfate. Equivalent to Q9CBA3|ML2279 putative transmembrane transport protein from Mycobacterium leprae (496 aa), FASTA scores: opt: 1637, E(): 1.8e-89, (59.15% identity in 487 aa overlap). Similar to various proteins (principally sulfate transporters) e.g. Q9X927|SCH5.25 putative integral membrane protein from Streptomyces coelicolor (830 aa), FASTA scores: opt: 1325, E(): 8e-71, (40.85% identity in 788 aa overlap); Q9I729|PA0103 probable sulfate transporter from Pseudomonas aeruginosa (523 aa), FASTA scores: opt: 1015, E(): 1.3e-52, (39.95% identity in 488 aa overlap); Q9KN88|VCA0077 sulfate permease family protein from Vibrio cholerae (553 aa), FASTA scores: opt: 629, E(): 9.6e-30, (30.95% identity in 423 aa overlap); etc. C-terminal part (aa 550-764) shows similarity to carbonic anhydrase e.g. P27134|CYNT_SYNP7 carbonic anhydrase (272 aa), FASTA scores: opt: 350, E(): 8.1e-15, (33.8% identity in 201 aa overlap). Contains PS00704 Prokaryotic-type carbonic anhydrases signature 1. Seems to belong to the SulP family.

ProteomicsIdentified 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 cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). 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 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 90 days but not 30 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).
TranscriptomicsmRNA identified by microarray analysis and down-regulated after 96h of starvation (see citation below).
MutantNon-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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
