Biochem/physiol Actions
Glyceraldehyde-3-phosphate dehydrogenase catalyzes the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate as part of glycolysis. It has also been shown to have roles in initiation of apoptosis, transcription activation and the shuttling of ER to Golgi vesicles<<<,New>>>.
Unit Definition
One unit will reduce 1.0 μmole of 3-phosphoglycerate to D-glyceraldehyde 3-phosphate per min in a coupled system with 3-phosphoglyceric phosphokinase at pH 7.6 at 25 °C.
Physical form
Lyophilized, sulfate-free powder stabilized with trehalose, citrate, and DTT. Useful for systems requiring low sulfate.

Although the classical redox functions of co-enzyme NAD(+) are firmly established in metabolism, there are numerous enzymes that catalyze cleavage of NAD(+) to yield free ADP-ribose (ADPr) or related metabolites, whose functions remain largely unknown. Here we show that the
