Two component sensor histidine kinase PrrB; Member of the two-component regulatory system PrrB/PrrA that is involved specifically in early intracellular multiplication of Mycobacterium and is essential for its viability. Functions as a sensor protein kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to the conserved aspartic acid residue in the regulatory domain of PrrA. In turn, PrrA binds to the upstream promoter regions of target genes including itself to positively regulate their expression.

Potassium-transporting ATPase potassium-binding subunit; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit binds and transports the potassium across the cytoplasmic membrane.

Rv1032c, (MTCY10G2.17), len: 509 aa. TrcS, two component sensor histidine kinase protein (see citations below), similar to YV16_MYCLE|P54883 probable sensor-like histidine kinase from Mycobacterium leprae (443 aa), FASTA scores: opt: 392, E(): 3.8e-18, (31.7% identity in 334 aa overlap). Note that in vitro autophosphorylation of TrcS requires the presence of Mn2+ or Ca2+ as a divalent cation cofactor and subsequent transphosphorylation of TrcR is evident in the presence of TrcS-phosphate and Ca2+.

Rv1033c, (MTCY10G2.16), len: 257 aa. TrcR,two-component regulatory protein (see citations below),similar to Q50825 two component response regulator from Mycobacterium tuberculosis (234 aa), FASTA scores: opt: 628, E(): 0, (46.0% identity in 226 aa overlap). Note that in vitro autophosphorylation of TrcS requires the presence of Mn2+or Ca2+as a divalent cation cofactor and subsequent transphosphorylation of TrcR is evident in the presence of TrcS-phosphate and Ca2+.

Potassium-transporting ATPase KdpC subunit; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit acts as a catalytic chaperone that increases the ATP-binding affinity of the ATP-hydrolyzing subunit KdpB by the formation of a transient KdpB/KdpC/ATP ternary complex.

Potassium-transporting ATPase ATP-binding subunit; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit is responsible for energy coupling to the transport system. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IA subfamily.

Rv2488c, (MTV008.44c), len: 1137 aa. Probable transcriptional regulatory protein, belonging to luxR family, similar to many in Mycobacterium tuberculosis e.g. AAK44621|MT0399 from strain CDC1551 (1092 aa) FASTA scores: opt: 3767, E(): 1.8e-211, (56.75% identity in 1093 aa overlap); O53720|Rv0386|MTV036.21 from strain H37Rv (1085 aa), FASTA scores: opt: 3756, E(): 7.6e-211, (56.75% identity in 1089 aa overlap); AAK45665|MT1402 from strain CDC1551 (1159 aa), FASTA scores: opt: 3395, E(): 8.2e-190,(52.0% identity in 1093 aa overlap); etc. Also similar to transcriptional regulatory protein [...]
