METK1_HUMAN Defects in MAT1A are the cause of methionine adenosyltransferase deficiency (MATD) [MIM:250850; also called MAT I/III deficiency. MATD is an inborn error of metabolism resulting in isolated hypermethioninemia. Most patients have no clinical abnormalities, although some neurologic symptoms may be present in rare cases with severe loss of methionine adenosyltransferase activity.[1][2][3][4]
Function
METK1_HUMAN Catalyzes the formation of S-adenosylmethionine from methionine and ATP.
