Enzyme Information
| 2.7.11.22 |
Cyclin-dependent kinase.
based on mapping to UniProt P06493
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.
|
| 2.7.11.23 |
[RNA-polymerase]-subunit kinase.
based on mapping to UniProt P06493
ATP + [DNA-directed RNA polymerase] = ADP + [DNA-directed RNA polymerase] phosphate.
-!- Appears to be distinct from other protein phosphokinases. -!- Brings about multiple phosphorylation of the unique C-terminal repeat domain of the largest subunit of eukaryotic EC 2.7.7.6. -!- Does not phosphorylate casein, phosvitin or histone. -!- Formerly EC 2.7.1.141.
