The laboratory FY23 strain of S. cerevisiae was used to evaluate the effect of the overexpression of the VIN13 CAT2 gene on ester production during alcoholic fermentation in yeast. We overexpressed CAT2 as protein encoded by this gene localizes to the peroxisomes and to mitochondria and contributes to more than 95% of total CrAT activity in oleate- and galactose-grown yeast cells
