Synthesis of non-natural cofactor analogs of S-adenosyl-L-methionine using methionine adenosyltransferase

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: where X is S or Se, and R1 is an alkyl group.

Rationally engineered variants of S-adenosylmethionine (SAM) synthase: Reduced product inhibition and synthesis of artificial cofactor homologues

S-Adenosylmethionine (SAM) synthase was engineered for biocatalytic production of SAM and long-chain analogues by rational re-design. Substitution of two conserved isoleucine residues extended the substrate spectrum of the enzyme to artificial S-alkylhomocysteines. The variants proved to be beneficial in preparative synthesis of SAM (and analogues) due to a much reduced product inhibition. This journal is

Facile chemoenzymatic strategies for the synthesis and utilization of S-adenosyl-L-methionine analogues

A chemoenzymatic platform for the synthesis of S-adenosyl-L-methionine (SAM) analogues compatible with downstream SAM-utilizing enzymes is reported. Forty-four non-native S/Se-alkylated Met analogues were synthesized and applied to probing the substrate specificity of five diverse methionine adenosyltransferases (MATs). Human MAT II was among the most permissive of the MATs analyzed and enabled the chemoenzymatic synthesis of 29 non-native SAM analogues. As a proof of concept for the feasibility of natural product alkylrandomization , a small set of differentially-alkylated indolocarbazole analogues was generated by using a coupled hMAT2-RebM system (RebM is the sugar C4′-O-methyltransferase that is involved in rebeccamycin biosynthesis). The ability to couple SAM synthesis and utilization in a single vessel circumvents issues associated with the rapid decomposition of SAM analogues and thereby opens the door for the further interrogation of a wide range of SAM utilizing enzymes. Mix and MATch: Methionine adenosyltransferase (MAT) was used to synthesize S-adenosylmethionine (SAM) analogues in a method directly compatible with downstream SAM-utilizing enzymes. As a proof of concept for the feasibility of natural product alkylrandomization by using this method, a coupled strategy in which MAT was applied in conjunction with the methyltransferase RebM was used to generate a small set of indolocarbazole analogues.
