Abstract


S-Adenosylmethionine (SAM) is a key component of sulphur amino acid metabolism in living organisms and is synthesised from methionine and adenosine triphosphate by methionine adenosyltransferase. This molecule serves as the main biological methyl donor due to its active methylthio ether group. Notably, SAM has shown beneficial effects in clinical trials for the treatment of alcoholic liver disease, depression and joint pain. Due to the high potential value of SAM, current research efforts are attempting to develop a more rapid, cost-effective and higher yielding SAM production method than the conventional production system. In this mini-review, we describe the previously reported yeast gene that contributes to SAM accumulation by overexpression, mutation or deletion and summarise the genetic approach for the production of SAM in large industrial quantities.
