General annotation
Gene nameptkA
Rv numberRv2232
FunctionInvolved in signal transduction (via phosphorylation). Can phosphorylate PTPA|Rv2234 and the peptide substrate myelin basic protein (MBP) [catalytic activity: ATP + a protein = ADP + a phosphoprotein]
ProductProtein tyrosine kinase transcriptional regulatory protein PtkA
CommentsRv2232, (MTCY427.13), len: 291 aa. PtkA, protein tyrosine kinase, similar to members of haloacid dehalogenase-like family from several bacteria and to putative phosphatases e.g. Q9I767 and AAK78398. Contains N-terminal extension. FASTA scores: Q9I767 hypothetical protein PA0065 (221 aa) opt: 439 E(): 3.2e-18; 38.679% identity (40.196% ungapped) in 212 aa overlap; >>tr|AAK78398 Predicted phosphatase, had family (216 aa) opt: 427, E(): 1.5e-17; 34.762% identity (35.437% ungapped) in 210 aa overlap. Replaces previous Rv2232 and Rv2233. Predicted to be an outer membrane protein (See Song et al., 2008).
