Protein

Tyrosine-protein kinase CpsD

Gene

cpsD

Organism
Streptococcus agalactiae
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

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 (By similarity).By similarity

Catalytic activityi

ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.

Enzyme regulationi

Dephosphorylated and activated by CpsB.By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
