CC -!- FUNCTION: Catalyzes the formation of S-adenosylmethionine (AdoMet) from
CC methionine and ATP. The overall synthetic reaction is composed of two
CC sequential steps, AdoMet formation and the subsequent tripolyphosphate
CC hydrolysis which occurs prior to release of AdoMet from the enzyme.
CC {ECO:0000255|HAMAP-Rule:MF_00086}.
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:0000255|HAMAP-Rule:MF_00086};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00086};
CC Note=Binds 2 divalent ions per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00086};
CC -!- COFACTOR:
CC Name=K(+); Xref=ChEBI:CHEBI:29103;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00086};
CC Note=Binds 1 potassium ion per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00086};
CC -!- PATHWAY: Amino-acid biosynthesis; S-adenosyl-L-methionine biosynthesis;
CC S-adenosyl-L-methionine from L-methionine: step 1/1.
CC {ECO:0000255|HAMAP-Rule:MF_00086}.
CC -!- SUBUNIT: Homotetramer; dimer of dimers. {ECO:0000255|HAMAP-
CC Rule:MF_00086}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00086}.
CC -!- SIMILARITY: Belongs to the AdoMet synthase family. {ECO:0000255|HAMAP-
CC Rule:MF_00086}.
