General annotation
FunctionInvolved in signal transduction (via phosphorylation). Thought to regulate morphological changes associated with cell division/differentiation process. Phosphorylates at serine and threonine residues [catalytic activity: ATP + a protein = ADP + a phosphoprotein].
ProductTransmembrane serine/threonine-protein kinase A PknA (protein kinase A) (STPK A)
CommentsRv0015c, (MTCY10H4.15c), len: 431 aa. PknA, transmembrane serine/threonine-protein kinase, magnesium/manganese dependent (see citations below). Contains PS00108 Serine/Threonine protein kinases active-site signature. Contains Hank's kinase subdomain. Belongs to the Ser/Thr family of protein kinases. It has been shown that sodium orthovanadate inhibits the activity of the enzyme in vitro.
Functional categoryRegulatory proteins
ProteomicsIdentified in the cytosol of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Predicted transmembrane protein - identified in culture filtrates of M. tuberculosis H37Rv; signal peptide predicted (See Malen et al., 2007). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 and 90 days (See Kruh et al., 2010).
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).
