CC -!- FUNCTION: Histone methyltransferase that specifically monomethylates
CC 'Lys-27' of histone H3 (H3K27me1). Has much higher activity on
CC nucleosomes containing H3.1 than H3.3. Involved in the formation of
CC constitutive heterochromatin and the silencing of heterochromatic
CC elements. {ECO:0000250|UniProtKB:Q8VZJ1}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-lysyl(27)-[histone H3] + S-adenosyl-L-methionine = H(+) +
CC N(6)-methyl-L-lysyl(27)-[histone H3] + S-adenosyl-L-homocysteine;

CC ChEBI:CHEBI:59789, ChEBI:CHEBI:61929; EC=2.1.1.369;
CC Evidence={ECO:0000250|UniProtKB:Q8VZJ1};
CC -!- SUBUNIT: Homodimer. {ECO:0000269|PubMed:24626927}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000250}. Nucleus
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the class V-like SAM-binding methyltransferase
CC superfamily. {ECO:0000255|PROSITE-ProRule:PRU00190}.
