ENZYME

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 2.7.99.1

Accepted Name
Triphosphate--protein phosphotransferase.
Alternative Name(s)
Diphosphate--protein phosphotransferase.
DiPPT.
Pyrophosphate-protein phosphotransferase.
Reaction catalysed
Triphosphate + [microsomal-membrane protein] <=> diphosphate + [microsomal-membrane protein] phosphate
Comment(s)
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 2.7.1.104.
