Enzyme Information
| 2.7.11.19 |
Phosphorylase kinase.
based on mapping to UniProt P62161
2 ATP + phosphorylase b = 2 ADP + phosphorylase a.
-!- Requires calmodulin for activity. -!- The enzyme phosphorylates a specific serine residue in each of the subunits of the dimeric phosphorylase b. -!- For muscle phosphorylase but not liver phosphorylase, this is accompanied by a further dimerization to form a tetrameric phosphorylase. -!- The enzyme couples muscle contraction with energy production via glycogenolysis--glycolysis by catalyzing the Ca(2+)-dependent phosphorylation and activation of glycogen phosphorylase b. -!- The gamma subunit of the tetrameric alpha-beta-gamma-delta enzyme is the catalytic subunit. -!- Formerly EC 2.7.1.38.

| 3.1.3.16 |
Protein-serine/threonine phosphatase.
based on mapping to UniProt P63329
[a protein]-serine/threonine phosphate + H(2)O = [a protein]- serine/threonine + phosphate.
-!- A group of enzymes removing the serine- or threonine-bound phosphate group from a wide range of phosphoproteins, including a number of enzymes which have been phosphorylated under the action of a kinase (cf. EC 3.1.3.48). -!- The spleen enzyme also acts on phenolic phosphates and phosphamides (cf. EC 3.9.1.1).
