METHIONINE ADENOSYLTRANSFERASE COMPLEXED WITH A L-METHIONINE ANALOGOUS
OverviewOverview
Methionine adenosyltransferases (MATs) are a family of enzymes in charge, of synthesising S-adenosylmethionine (SAM), the most important methyl, donor present in living organisms. These enzymes use methionine and ATP as, reaction substrates, which react in a S(N)2 fashion where the sulphur atom, from methionine attacks C5' from ATP while triphosphate chain is cleaved., A MAT liver specific isoenzyme has been detected, which exists in two, distinct oligomeric forms, a dimer (MAT III) and a tetramer (MAT I). Our, previously reported crystal structure of MAT I complexed with an inhibitor, led to the identification of the methionine-binding site. We present here, the results obtained from the complex of MAT I with a competitive, inhibitor of methionine, (2S,4S)-amino-4,5-epoxypentanoic acid ... [(full description)]
