Abstract: Glutamate dehydrogenase (GDH, EC 1.4.1.2~4) are the enzymes which catalyze reversible deamination reaction of L-glutamate to 2-oxoglutarate or -ketoglutarate (-KG). We identified a total of ten GDH encoded genes in soybean genome. The full length sequence of predicted proteins had 637 or 411 amino acids, except GmGDH06. Analysis of p...
