Description	Glyceraldehyde-3-phosphate dehydrogenase [GAPDH, NAD + oxidoreductase (phosphorylating) 1.2.1.12] catalyzes the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate coupled with the reduction of NAD(+) to NADH. In addition to its role in glycolysis, this enzyme has numerous alternate functions, in both prokaryotes and eukaryotes. In plants, additional functions have been reported from multiple species including Pisum sativum. A recent study has identified that GAPDH may play an important role in seed ageing and programmed cell death. Despite this the existing purification protocols are almost 40 years old, and only partial characterization of the enzyme has been reported. In the current study, we report a modified method for purification of enzymatically active pea seed GAPDH along with the characterization of the enzyme. Using 2D gel electrophoresis our study also demonstrates that pea seeds contain four isoforms of NAD(+) dependent GAPDH.
