General annotation
Gene namekdpC
Rv numberRv1031
FunctionOne of the components of the high-affinity ATP-driven potassium transport (or KDP) system, which catalyzes the hydrolysis of ATP coupled with the exchange of hydrogen and potassium ions. The C subunit may be involved in assembly of the KDP complex. [catalytic activity: ATP + H(2)O + K(+)(out) = ADP + phosphate + K(+)(in)].
ProductProbable potassium-transporting ATPase C chain KdpC (potassium-translocating ATPase C chain) (ATP phosphohydrolase [potassium-transporting] C chain) (potassium binding and translocating subunit C)
CommentsRv1031, (MTCY10G2.18c), len: 189 aa. Probable kdpC, potassium-transporting ATPase C chain (membrane protein) , similar to others e.g. ATKC_ECOLI|P03961 potassium-transporting ATPase C chain from Escherichia coli strain K12 (190 aa), FASTA scores: opt: 475, E(): 3.1e-24, (45.7% identity in 186 aa overlap); etc. Belongs to the KdpC family.

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 of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011).
Mutationnon essential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Check for mutants available at TARGET website
