Autophosphorylation of CpsD attenuates its activity and reduces the level of encapsulation. May be part of a complex that directs the coordinated polymerization and export to the cell surface of the capsular polysaccharide (By similarity).ATP + L-tyrosyl-[protein] = ADP + H(+) + O-phospho-L-tyrosyl-[protein]Dephosphorylated and activated by CpsB.Capsule biogenesis; capsule polysaccharide biosynthesis.Autophosphorylated.Belongs to the CpsD/CapB family.ATP-bindingCapsule biogenesis/degradationExopolysaccharide synthesisKinaseNucleotide-bindingPhosphoproteinReference proteomeTransferaseTyrosine-protein kinaseMPTLEIAQKKLEFIKKAEEYYNALCTNIQLSGDKLKVISVTSVNPGEGKTTTSINIAWSFARAGYKTLLIDGDTRNSVMLGVFKSREKITGLTEFLSGTADLSHGLCDTNIENLFVVQSGSVSPNPTALLQSKNFNDMIETLRKYFDYIIIDTPPIGIVIDAAIITQKCDASILVTATGEANKRDIQKAKQQLKQTGKLFLGVVLNKLDISVNKYGVYGSYGNYGKK
