Protein kinases and phosphatases

These enzymes phosphorylate or dephosphorylate other proteins. By definition, they use ATP (or GTP) as the phosphoryl group donor (as opposed to phosphotransferases of the phosphotranferase system and the phosphorelay).

Protein kinases

Protein serine kinases

• HprK (has also phosphorylase activity)
• PrkC
• PrkD
• RsbT
• RsbW
• SpoIIAB
• YabT

Protein tyrosine kinases, see the Bacterial Protein Tyrosine Kinase Database)

• PtkA
• EpsB: similar to PtkA, but has probably no kinase activity
