Phosphorylates the FHA domains of the ABC transporter Rv1747, the heat-shock protein GroEL 1, and Rv0020c. May play a role in the regulation of glucose transport, cell growth and septum formation. ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-[protein] ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-threonyl-[protein] Interacts with Rv1747. Autophosphorylated. Dephosphorylated by PstP. Disruption does not attenuate growth in macrophages. Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
