2.7.7.27 3-phosphoglycerate
-
Oryza sativa
2.7.7.27 3-phosphoglycerate the activities of recombinant maize and recombinant potato enzyme are comparable in the presence of 10 mM 3-phosphoglycerate, however in absence of 3-phosphoglycerate and phosphate the maize enzyme exhibits approximately 20fold more activity than does potato enzyme, in presence of both 3-phosphoglycerate and phosphate the maize enzyme is 47fold active than is the potato enzyme Zea mays
