General annotation
FunctionEssential for recycling GMP and indirectly, CGMP [catalytic activity: ATP + GMP = ADP + GDP]
ProductProbable guanylate kinase Gmk
CommentsRv1389, (MTCY21B4.06), len: 208 aa. Probable gmk, guanylate kinase, similar to e.g. KGUA_ECOLI|P24234 guanylate kinase from Escherichia coli (207 aa), FASTA scores: opt: 424, E(): 6.6e-20, (35.9% identity in 184 aa overlap). Contains PS00017 ATP/GTP-binding site motif A (P-loop), PS00856 Guanylate kinase signature. Belongs to the guanylate kinase family.
Functional categoryIntermediary metabolism and respiration
ProteomicsIdentified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen 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). Translational start site supported by proteomics data (See Kelkar et al., 2011).
MutantEssential 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).
