Phosphotransferase (PT) are enzymes which catalyze phosphorylation reactions. The acceptor group can be alcohol, carboxy, nitrogenous, phosphate or a pair ofd groups.

• Aminoglycoside PT (AGPT) inactivate aminoglycoside antibiotics by phosphorylation.
  
• Phosphoenolpyruvate-protein PT (PEP) catalyzes the phosphorylation of protein histidine residues.
