CC -!- FUNCTION: Involved in a key methylation step in both tocopherols
CC (vitamin E) and plastoquinone synthesis. Catalyzes the conversion of 2-
CC methyl-6-phytyl-1,4-hydroquinone (MPBQ) to 2,3-dimethyl-6-phytyl-1,4-
CC hydroquinone (DMPQ, a substrate for tocopherol cyclase), and 2-methyl-
CC 6-solanyl-1,4-benzoquinone (MSBQ) to plastoquinone (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2-methyl-6-phytyl-1,4-benzene-1,4-diol + S-adenosyl-L-
CC methionine = 2,3-dimethyl-6-phytylbenzene-1,4-diol + H(+) + S-
CC adenosyl-L-homocysteine; Xref=Rhea:RHEA:37979, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:75920,
CC ChEBI:CHEBI:75921; EC=2.1.1.295;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2-methyl-6-all-trans-nonaprenylbenzene-1,4-diol + S-adenosyl-
CC L-methionine = H(+) + plastoquinol-9 + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:37999, ChEBI:CHEBI:15378, ChEBI:CHEBI:28026,
CC ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:75402;
CC EC=2.1.1.295;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=6-geranylgeranyl-2-methylbenzene-1,4-diol + S-adenosyl-L-
CC methionine = 6-geranylgeranyl-2,3-dimethylbenzene-1,4-diol + H(+) +
CC S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:38007, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:75411,
CC ChEBI:CHEBI:75412; EC=2.1.1.295;
CC -!- PATHWAY: Cofactor biosynthesis; tocopherol biosynthesis.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast inner membrane
CC {ECO:0000250}; Single-pass membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. MPBQ/MBSQ MT family. {ECO:0000255|PROSITE-
