AC PRU00914; DC Domain; TR PROSITE; PS51581; SAM_GTMT; 1; level=0 XX Names: Gammma-tocopherol O-methyltransferase (gTMT) Function: Tocopherol O-methyltransferase (EC 2.1.1.95) is an enzyme that transfers a methyl group from S-adenosyl-L-methionine (SAM) to gamma- tocopherol to form alpha-tocopherol and S-adenosyl-L-homocysteine. The cyanobacterial orthologue sll0418 (EC 2.1.1.295) methylates 2-methyl-6- phytyl-1,4-benzoquinone/2-methyl-6-solanyl-1,4-benzoquinone (MPBQ/MSBQ) to yield 2,3-dimethyl-5-phytylbenzoquinone/2,3-dimethyl/plastoquinol-9. XX CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase CC superfamily. gTMT family.
