Enzyme Information

2.7.11.22

Cyclin-dependent kinase.

based on mapping to UniProt P24941

ATP + a protein = ADP + a phosphoprotein.

-!- Activation of cyclin-dependent kinases requires association of the enzyme with a regulatory subunit referred to as a cyclin. -!- It is the sequential activation and inactivation of cyclin-dependent kinases, through the periodic synthesis and destruction of cyclins, that provides the primary means of cell-cycle regulation. -!- Formerly EC 2.7.1.37.
