<prompt> Used in Transamination:Pyridoxal phosphateNADPHNADPFAD  <response>: Transamination first step in the catabolism of amino acids is catalysed by transaminases. These enzymes use pyridoxal phosphate which is active form of pyridoxine vitamin B6 as coenzyme. Biochemical Roles of Pyridoxine Trans-sulfuration Simple decarboxylation mainly histidine, gluatamate, tryptophan ALA synthase Haem synthesis Cystathionine synthase synthesis of Cysteine Alkaline phosphatase Glycogen phosphorylase RLE in glycogen breakdown Tryptophan metabolism, synthesis of Niacin vitamin B3
