Protein
Tyrosine-protein kinase CpsD
Organism
Streptococcus agalactiae serotype Ia (strain ATCC 27591 / A909 / CDC SS700)
Function
Involved in the regulation of capsular polysaccharide biosynthesis. 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.
Similarity
Belongs to the CpsD/CapB family.
