General Information

EC Number General Information Comment Organism
1.1.1.270 physiological function loss of the 3-keto reductase also results in a concomitant loss of activity of the upstream oxidosqualene cyclase. Oxidosqualene cyclase is not required for the 3-ketoreductase activity. In Saccharomyces cerevisiae, the protective relationship between the 3-keto reductase Erg27 and oxidosqualene cyclase Erg7p is not reciprocal Saccharomyces cerevisiae
