Methionine adenosyltransferase II, beta (MAT II beta) belongs to the methionine adenosyltransferase (MAT) family. MAT II beta catalyzes the biosynthesis of S-adenosylmethionine from methionine and ATP. This protein is the regulatory beta subunit of MAT. Its expression in hepatoma cell lines may lead to increase DNA synthesis and thereby participate to cell proliferation. Recombinant human MAT II beta was expressed in E. coli and purified by using conventional chromatography techniques.
