Protein

S-adenosylmethionine synthase

Gene

Mat2a

Organism
Mus musculus (Mouse)
Status
Unreviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the formation of S-adenosylmethionine from methionine and ATP.UniRule annotation

Catalytic activityi

ATP + L-methionine + H2O = phosphate + diphosphate + S-adenosyl-L-methionine.UniRule annotation

Cofactori

Protein has several cofactor binding sites:
  • K+UniRule annotationNote: Binds 1 potassium ion per subunit. The potassium ion interacts primarily with the substrate.UniRule annotation
  • Mg2+UniRule annotationNote: Binds 2 magnesium ions per subunit. The magnesium ions interact primarily with the substrate.UniRule annotation

Pathwayi: S-adenosyl-L-methionine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes S-adenosyl-L-methionine from L-methionine.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. S-adenosylmethionine synthase (Mat2a), Methionine adenosyltransferase 2 subunit beta (Mat2b), S-adenosylmethionine synthase isoform type-2 (Mat2a), S-adenosylmethionine synthase (Mat2a), S-adenosylmethionine synthase (Mat2a), S-adenosylmethionine synthase isoform type-1 (Mat1a), Methionine adenosyltransferase 2 subunit beta (Mat2b), S-adenosylmethionine synthase (Mat2a), S-adenosylmethionine synthase (Mat2a), S-adenosylmethionine synthase (Mat2a), S-adenosylmethionine synthase (Mat2a), S-adenosylmethionine synthase (Mat2a)
This subpathway is part of the pathway S-adenosyl-L-methionine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes S-adenosyl-L-methionine from L-methionine, the pathway S-adenosyl-L-methionine biosynthesis and in Amino-acid biosynthesis.
