Biol. Chem. 283:8023-8033(2008). CC -!- FUNCTION: Protein kinase that regulates many aspects of mycobacterial CC physiology. Is a key component of a signal transduction pathway that CC regulates cell growth, cell shape and cell division via phosphorylation CC of target proteins such as FtsZ and MurD. Shows a strong preference for CC Thr versus Ser as the phosphoacceptor. {ECO:0000269|PubMed:11856348, CC ECO:0000269|PubMed:17068335, ECO:0000269|PubMed:18557704}.
