EXPRESSION
ORGANISM
UNIPROT
LITERATURE
a slight increase in enzyme activity is observed in the presence of D-fructose 6-phosphate and coenzyme A (1.1fold)
-
ATP, ADP, AMP, D-glucose 6-phosphate and galactose 1-phosphate exhibit no effect on enzyme activity
-
downregulation of GAPDH in the dark
-
expression of isoforms GapA-1, GapB and phosphoribulokinase and peptide Cp12-2 is co-ordinately regulated with the same organ specificity, all four genes being mostly expressed in leaf and flower stalk, less expressed in flower, and little or not expressed in roots and siliques. Expression in leaf is terminated during prolonged darkness or following sucrose treatment, and their transcripts decay with similar kinetics
