FunctiondGTPase preferentially hydrolyzes dGTP over the other canonical NTPS [catalytic activity: dGTP + H(2)O = deoxyguanosine + triphosphate].
ProductProbable deoxyguanosine triphosphate triphosphohydrolase Dgt (dGTPase) (dGTP triphosphohydrolase)
CommentsRv2344c, (MT2409, MTCY98.13c), len: 431 aa. Probable dgt, deoxyguanosine triphosphate triphosphohydrolase, equivalent to Q9CCG3|DGT|ML0831 putative deoxyguanosine triphosphate triphosphohydrolase from Mycobacterium leprae (429 aa), FASTA scores: opt: 2316, E(): 1.6e-137, (83.85% identity in 421 aa overlap); and O52199|DGTP_MYCSM|AF027507_2 deoxyguanosinetriphosphate triphosphohydrolase from Mycobacterium smegmatis (428 aa), FASTA scores: opt: 1991, E(): 3.4e-117, (73.5% identity in 422 aa overlap). Also highly similar or similar to several deoxyguanosine triphosphate hydrolases e.g. Q9L2E9|SC7A8.09c putative deoxyguanosinetriphosphate triphosphohydrolase from Streptomyces coelicolor (424 aa), FASTA scores: opt: 1216, E(): 1e-68, (51.05% identity in 425 aa overlap); BAB48544|MLL1093 dGTP triphosphohydrolase from Rhizobium loti (Mesorhizobium loti) (404 aa), FASTA scores: opt: 489, E(): 3.1e-23, (33.85% identity in 387 aa overlap); P15723|DGTP_ECOLI|DGT|B0160 from Escherichia coli strain K12 (504 aa), FASTA scores: opt: 173, E(): 0.0022, (31.65% identity in 259 aa overlap); etc. Belongs to the dGTPase family.
Functional categoryIntermediary metabolism and respiration
ProteomicsIdentified 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 membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega 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). Translational start site supported by proteomics data (See Kelkar et al., 2011).
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 strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
