when brassica nigra leaf petiole suspension cells were subjected to 7 days of inorganic phosphate ( pi ) starvation the extractable activity of : ( a ) pyrophosphate : fructose 6-phosphate 1-phosphotransferase , nonphosphorylating nadp-glyceraldehyde 3-phosphate dehydrogenase , phosphoenolpyruvate phosphatase , and phosphoenolpyruvate carboxylase increased at least fivefold , ( b ) phosphorylating nad-glyceraldehyde 3-phosphate dehydrogenase decreased about sixfold , and ( c ) atp : fructose 6-phosphate 1-phosphotransferase , 3-phosphoglycerate kinase , pyruvate kinase , or nad malic enzyme was not altered .
