comment
  • FUNCTION Involved in the synthesis of tocopherol (vitamin E). Methylates gamma- and delta-tocopherol to form beta- and alpha-tocopherol, respectively.CATALYTIC ACTIVITY gamma-tocopherol + S-adenosyl-L-methionine = (+)-alpha-tocopherol + S-adenosyl-L-homocysteine + H(+)CATALYTIC ACTIVITY delta-tocotrienol + S-adenosyl-L-methionine = beta-tocotrienol + S-adenosyl-L-homocysteine + H(+)CATALYTIC ACTIVITY gamma-tocotrienol + S-adenosyl-L-methionine = alpha-tocotrienol + S-adenosyl-L-homocysteine + H(+)CATALYTIC ACTIVITY delta-tocopherol + S-adenosyl-L-methionine = beta-tocopherol + S-adenosyl-L-homocysteine + H(+)PATHWAY Cofactor biosynthesis; tocopherol biosynthesis.SUBCELLULAR LOCATION Belongs to the class I-like SAM-binding methyltransferase superfamily. gTMT family.
