The reaction starts with imine formation between pyridoxamine 5'-phosphate and the aldehyde of GSA. During the first half of the reaction pyridoxamine 5'-phosphate is converted to pyridoxal 5'-phosphate, while pyridoxamine 5'-phosphate is regenerated in the second half of the reaction upon 5-aminolevulinate formation Arabidopsis thaliana ? - ? 89
