CC   -!- FUNCTION: Involved in the regulation of capsular polysaccharide
CC       biosynthesis. Autophosphorylation of CpsD attenuates its activity and
CC       reduces the level of encapsulation. May be part of a complex that
CC       directs the coordinated polymerization and export to the cell surface
CC       of the capsular polysaccharide. {ECO:0000269|PubMed:11027683}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + L-tyrosyl-[protein] = ADP + H(+) + O-phospho-L-tyrosyl-

CC         ChEBI:CHEBI:82620, ChEBI:CHEBI:456216; EC=2.7.10.2;
CC   -!- ACTIVITY REGULATION: Dephosphorylated and activated by CpsB.
CC       {ECO:0000250}.
CC   -!- PATHWAY: Capsule biogenesis; capsule polysaccharide biosynthesis.
CC   -!- PTM: Autophosphorylated. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the CpsD/CapB family. {ECO:0000305}.
