What is PLP cofactor

What is PLP cofactor

Some of these enzymes are listed in table 9.3.Vitamin b 6) is a chromophoric cofactor required for catalytic activity by a wide variety of enzymes.Tryptophan, the cofactor plp (vitamin b6) is required.The aldehyde group of pyridoxal phosphate forms a.What is the vitamin of nad+ and nadp+?

In the aminotransferases, the cofactor form shifts between plp and pmp.Pyridoxal phosphate (plp) is an organic cofactor found in all transaminase enzymes.Due to its role as a cofactor in many enzymatic reactions, pyridoxal phosphate (plp) has been determined to be the biologically active form of vitamin b6.There are two different routes of de novo plp synthesis present in different organisms.
