EC 2.1.1.318     
Accepted name: [trehalose-6-phosphate synthase]-L-cysteine S-methyltransferase
Reaction: S-adenosyl-L-methionine + [trehalose-6-phosphate synthase]-L-cysteine = S-adenosyl-L-homocysteine + [trehalose-6-phosphate synthase]-S-methyl-L-cysteine
Systematic name: S-adenosyl-L-methionine:[trehalose-6-phosphate synthase]-L-cysteine S-methyltransferase
Comments: The enzyme, characterized from the yeast Saccharomyces cerevisiae, enhances the activity of EC 2.4.1.15, trehalose-6-phosphate synthase, resulting in elevating the levels of trehalose in the cell and contributing to stationary phase survival. In vitro the enzyme performs S-methylation of L-cysteine residues of various protein substrates.
