Protein Variants

Protein Variants Comment Organism
D228N reduced apparent affinity for the activator glycine Zea mays
E229A maximal activation caused by glycine is greatly reduced, significantly lowered sensitivity to the inhibitors malate and aspartate. K(0.5) for phosphoenolpyruvate is lower than wild-type value Zea mays
R226Q maximal activation caused by glycine is greatly reduced, significantly lowered sensitivity to the inhibitors malate and aspartate. K(0.5) for phosphoenolpyruvate is significantly higher than that of wild-type enzyme Zea mays
R231A decreased apparent affinity for the activator glucose 6-phosphate Zea mays
R232Q decreased apparent affinity for the activator glucose 6-phosphate, reduced apparent affinity for the activator glycine Zea mays
