Chains	Enzyme Name	Description	Catalytic Residues
A	phosphorylase kinase M-CSA #35	Eukaryotic protein kinases catalyse the transfer of ATP-gamma phosphate to serine, threonine and tyrosine residues on specific target proteins. The family of protein kinases represents one of the largest protein superfamilies, and structures of active kinases show similar conformations in key regions involved in ATP and protein substrate recognition domains. Phosphorylase kinase, the first protein kinase to be discovered, catalyses the phosphorylation of a single serine residue, Ser14 of inactive phosphorylase B (GPb). Phosphorylation converts the protein to active glycogen phosphorylase A (GPa), which catalyses glycogen degredation.
