(Pyruvate, phosphate dikinase)-phosphate phosphotransferase (, ''PPDK regulatory protein'', ''pyruvate, phosphate dikinase regulatory protein'', ''bifunctional dikinase regulatory protein'', ''PDRP1 (gene)'') is an
enzyme with
systematic name ''(pyruvate, phosphate dikinase) phosphate:phosphate phosphotransferase''.
This enzyme
catalyses the following
chemical reaction
:
yruvate, phosphate dikinasephosphate +
phosphate yruvate, phosphate dikinase+
diphosphate
The enzyme from the plants
maize and
arabidopsis
''Arabidopsis'' (rockcress) is a genus in the family Brassicaceae. They are small flowering plants related to cabbage and mustard. This genus is of great interest since it contains thale cress (''Arabidopsis thaliana''), one of the model organi ...
is bifunctional and also catalyses the
phosphorylation
In chemistry, phosphorylation is the attachment of a phosphate group to a molecule or an ion. This process and its inverse, dephosphorylation, are common in biology and could be driven by natural selection. Text was copied from this source, wh ...
