General annotation
Gene nametrcR
Rv numberRv1033c
FunctionSensor part of the two component regulatory system TRCS/TRCR. Involved in transcriptional autoactivation: TRCR activates its own expression by interacting with the at-rich sequence of the TRCR promoter.
ProductTwo component transcriptional regulator TrcR
CommentsRv1033c, (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+.
Molecular mass (Da)29209.4
