专利号:US-9879043-B1 优先权日:2013-06-06 标 题:Synthesis of non-natural cofactor analogs of S-adenosyl-L-methionine using methionine adenosyltransferase 发明人:THORSON JON; HUBER TYLER; ZHANG JIANJUN; Singh Shanteri 权利人:UNIV KENTUCKY RES FOUND 摘要:The present disclosure relates to the synthesis of non-natural analogs of S-adenosyl-L-methionine (SAM) and/or of Se-adenosyl-L-methionine (SeAM) by reacting a methionine analog and adenosine triphosphate (ATP) in the presence of at least one methionine adenosyltransferase (MAT), and to use thereof with downstream SAM and/or SeAM utilizing enzymes. The non-natural analogs of SAM and/or SeAM have the general formula: n nwhere X is S or Se, and R 1 is an alkyl group.
