S-adenosyl-L-methionine + [albumin]-L-cysteine

S-adenosyl-L-homocysteine + [albumin]-S-methyl-L-cysteine

Saccharomyces cerevisiae

I6WHP7

in vitro, the activity of the purified enzyme predominantly corresponds with the cysteine content of the substrates and is not specific for trehalose-6-phosphate synthase

Saccharomyces cerevisiae

I6WHP7

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
