it was confirmed that n- ( 5'-phosphopyridoxyl ) -l-serine was degradedly oxidized to pyridoxal 5'-phosphate and l-serine by the immobilized enzyme as comparable rate as pyridoxine 5'-phosphate , whereas n- ( 5'-phosphopyridoxyl ) -d-serine did not serve as substrate , as in the purified , soluble enzyme .
