Biol. Chem. 283:8023-8033(2008). CC -!- FUNCTION: Key component of a signal transduction pathway that CC regulates cell growth and cell division via phosphorylation of CC target proteins such as FtsZ and MurD. Shows a strong preference CC for Thr versus Ser as the phosphoacceptor. CC -!- CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. CC -!- ENZYME REGULATION: Activated by magnesium or manganese. Inhibited CC by vanadate. CC -!- SUBUNIT: Interacts with FtsZ and MurD. CC -!- SUBCELLULAR LOCATION: Cell membrane; Single-pass membrane protein CC (By similarity). CC -!- DOMAIN: The kinase domain and the juxtamembrane region contitute CC the catalytic core of PknA. Interaction between core and C- CC terminal domains is crucial for activity. CC -!- PTM: Autophosphorylated. CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr CC protein kinase family. CC -!- SIMILARITY: Contains 1 protein kinase domain.
