17631143-1	2007	BACKGROUND & AIMS: Two genes (MAT1A and MAT2A) encode for methionine adenosyltransferase, an essential enzyme responsible for S-adenosylmethionine (SAMe) biosynthesis.	Adenosine Monophosphate	12-15	methionine adenosyltransferase 2A	Homo sapiens	44-49	
12671891-1	2003	BACKGROUND & AIMS: Of the 2 genes (MAT1A, MAT2A) encoding methionine adenosyltransferase, the enzyme that synthesizes S-adenosylmethionine, MAT1A, is expressed in liver, whereas MAT2A is expressed in extrahepatic tissues.	Adenosine Monophosphate	12-15	methionine adenosyltransferase 2A	Homo sapiens	46-51
