Accepted name: isoamyl acetate esterase
Reaction: 3-methylbutyl acetate + H2O = 3-methylbutanol + acetate
Other name(s): IAH1 (gene name)
Systematic name: 3-methylbutyl acetate acetohydrolase
Comments: The enzyme, characterized from the yeast Saccharomyces cerevisiae, hydrolyses acetate esters. It acts preferentially on 3-methylbutyl acetate, a major determinant of sake flavor.
