[https://www.uniprot.org/uniprot/METK_SACS2 METK_SACS2] Catalyzes the formation of S-adenosylmethionine from methionine and ATP.[HAMAP-Rule:MF_00136]
<div style="background-color:#fffaf0;">
== Publication Abstract from PubMed ==
SMNF: Methionine adenosyltransferase (MAT) is a family of enzymes that utilizes ATP and methionine to produce S-adenosylmethionine (AdoMet), the most crucial methyl donor in the biological methylation of biomolecules and bioactive natural products. Here, we report that the MAT from Sulfolobus solfataricus (sMAT), an enzyme from a poorly explored class of the MAT family, has the ability to produce a range of differentially alkylated AdoMet analogs in the presence of non-native methionine analogs and ATP. To investigate the molecular basis for AdoMet analog production, we have crystallized the sMAT in the AdoMet bound, S-adenosylethionine (AdoMet) bound, and unbound forms. Notably, among these structures, the AdoEth-bound form offers the first MAT structure containing a non-native product and cumulatively, these structures add new structural insight into the MAT family and allow for detailed active site comparison with its homologs in E. coli and human. As a thermostable MAT structure from archaea, the structures herein also provide as a basis for future engineering to potentially broaden AdoMet analog production as reagents for methyltransferase-catalyzed 'alkylrandomization' and/or the study of methylation in the context of biological processes.
