phosphoribulokinase

phosphoribulokinase

 [fos″fo-ri″bu-lo-ki´nās]
an enzyme that catalyzes the conversion of ATP and d-ribulose 5-phosphate to ADP and d-ribulose 1,5-diphosphate.

phos·pho·ri·bu·lo·ki·nase

(fos'fō-rī'byū-lō-kī'nās),
An enzyme that, in the presence of ATP, catalyzes the phosphorylation of d-ribulose 5-phosphate to d-ribulose 1,5-bisphosphate and ADP, a reaction of importance in the carbon dioxide fixation cycle of photosynthesis.
