2.1.1.318	S-adenosyl-L-methionine + [trehalose-6-phosphate synthase]-L-cysteine	the enzyme performs S-methylation at cysteine residue regulating trehalose-6-phosphate synthase activity by 50%, which results in an increase of the intercellular stress sugar, trehalose. It contributes to stationary phase survival of Saccharomyces cerevisiae by elevating the levels of trehalose in the cell as it enters the stationary phase
