A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC

Accepted Name
Triphosphate--protein phosphotransferase.
Alternative Name(s)
Diphosphate--protein phosphotransferase.
Pyrophosphate-protein phosphotransferase.
Reaction catalysed
Triphosphate + [microsomal-membrane protein] <=> diphosphate + [microsomal-membrane protein] phosphate
  • This enzyme was originally thought to use diphosphate as substrate but this has since been disproved.
  • The activity is observed as the second part of a biphasic reaction after depletion of ATP.
  • Tripolyphosphate is a contaminant of (gamma-(32)P)ATP.
  • Formerly EC
