Sysname

S-adenosyl-L-methionine:gamma-tocopherol 5-C-methyltransferase

Reaction(IUBMB)

(1) S-adenosyl-L-methionine + gamma-tocopherol = S-adenosyl-L-homocysteine + alpha-tocopherol  [RN:R07236];
(2) S-adenosyl-L-methionine + delta-tocopherol = S-adenosyl-L-homocysteine + beta-tocopherol  [RN:R07504];
(3) S-adenosyl-L-methionine + gamma-tocotrienol = S-adenosyl-L-homocysteine + alpha-tocotrienol  [RN:R10491];
(4) S-adenosyl-L-methionine + delta-tocotrienol = S-adenosyl-L-homocysteine + beta-tocotrienol [RN:R10492]

Reaction(KEGG)

R07236 R07504 R10491 R10492

Substrate

S-adenosyl-L-methionine [CPD:C00019];
gamma-tocopherol [CPD:C02483];
delta-tocopherol [CPD:C14151];
gamma-tocotrienol [CPD:C14155];
delta-tocotrienol [CPD:C14156]

Product

S-adenosyl-L-homocysteine [CPD:C00021];
alpha-tocopherol [CPD:C02477];
beta-tocopherol [CPD:C14152];
alpha-tocotrienol [CPD:C14153];
beta-tocotrienol [CPD:C14154]

Comment

The enzymes from plants and photosynthetic bacteria have similar efficiency with the gamma and delta isomers of tocopherols and tocotrienols.
