Enables methionine adenosyltransferase activity. Involved in S-adenosylmethionine biosynthetic process and methionine metabolic process. Located in cytoplasmic stress granule. Human ortholog(s) of this gene implicated in hypermethioninemia and lung cancer. Orthologous to several human genes including MAT1A (methionine adenosyltransferase 1A).
SGD Description
S-adenosylmethionine synthetase; catalyzes transfer of the adenosyl group of ATP to the sulfur atom of methionine; comparative analysis suggests that a mitochondrially targeted form may result from translation starting at a non-canonical codon upstream of the annotated start codon
