Phosphocarrier protein
The mechanism involves the transfer of a phosphoryl group from phosphoenolpyruvate (PEP) via enzyme I (EI) to enzyme II (EII) of the PTS system, which There is a conserved histidine in the N-terminus of HPr, which serves as an acceptor for the phosphoryl group of EI.

Deoxycytidine kinase
This has deemed the "closed" conformation as the catalytically active conformation since it catalyzes the phosphoryl transfer between phosphoryl donors groups. dCK's closed (active) conformation allows dCK to transfer phosphoryl groups, but not bind or release nucleosides.

Adenylate kinase
of AMP on the γ-phosphoryl group of ATP resulting in formation of ADP by transfer of the γ-phosphoryl group to AMP. These sequential phosphotransfer relays ultimately result in propagation of the phosphoryl groups along collections of ADK molecules.
