CC -!- FUNCTION: Catalyzes the formation of S-adenosylmethionine from
CC methionine and ATP. The reaction comprises two steps that are both
CC catalyzed by the same enzyme: formation of S-adenosylmethionine
CC (AdoMet) and triphosphate, and subsequent hydrolysis of the
CC triphosphate. {ECO:0000250|UniProtKB:Q96551}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + L-methionine = diphosphate + phosphate + S-
CC adenosyl-L-methionine; Xref=Rhea:RHEA:21080, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:57844, ChEBI:CHEBI:59789; EC=2.5.1.6;
CC Evidence={ECO:0000250|UniProtKB:Q96551};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000250|UniProtKB:Q96551};
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:Q96551};
CC Name=Co(2+); Xref=ChEBI:CHEBI:48828;
CC Evidence={ECO:0000250|UniProtKB:Q96551};
CC Note=Binds 2 divalent ions per subunit. The metal ions interact
CC primarily with the substrate (By similarity). Can utilize magnesium,
CC manganese or cobalt (in vitro) (By similarity).
CC {ECO:0000250|UniProtKB:P13444, ECO:0000250|UniProtKB:Q96551};
CC -!- COFACTOR:
CC Name=K(+); Xref=ChEBI:CHEBI:29103;
CC Evidence={ECO:0000250|UniProtKB:Q96551};
CC Note=Binds 1 potassium ion per subunit. The potassium ion interacts
CC primarily with the substrate (By similarity).
CC {ECO:0000250|UniProtKB:P13444};
CC -!- PATHWAY: Amino-acid biosynthesis; S-adenosyl-L-methionine biosynthesis;
CC S-adenosyl-L-methionine from L-methionine: step 1/1.
CC {ECO:0000250|UniProtKB:Q96551}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the AdoMet synthase family. {ECO:0000305}.
