Quaternary structure
Function 1
Function descriptionGAPDH, converts D-glyceraldehyde 3-phosphate (G3P) into 3-phospho-D-glyceroyl phosphate, enzyme in glycolysis, glyceraldehyde 3-phosphate + phosphate + NAD+ => 3-phospho-D-glyceroyl phosphate + NADH

Commentswhen GAPDH is S-nitrosylated, increased binding to Siah1 and move to nucleus, some evidence that this function is also in mice and humans
