Esters 87-93 aspartate transaminase AAT2 Saccharomyces cerevisiae S288C 62-66 11985619-1 2002 Two genes (CM-AAT1 and CM-AAT2) with strong sequence homology (87% identity at the protein level) putatively involved in the formation of aroma volatile esters have been isolated from Charentais melon fruit. Esters 153-159 aspartate transaminase AAT2 Saccharomyces cerevisiae S288C 26-30
