Yeasts can convert amino acids to flavor alcohols following the Ehrlich pathway, a reaction sequence comprising transamination, decarboxylation, and reduction. The alcohols can be further derivatized to the acetate esters by alcohol acetyl transferase. Using L: -methionine as sole nitrogen

Carcinogenic benzo[a]pyrene (BP) is generally considered to show genotoxicity by forming DNA adducts of its metabolite, BP-7,8-diol-9,10-epoxide. We investigated oxidative DNA damage and its sequence specificity induced by BP-7,8-dione, another metabolite of BP, using (32)P-5'-end-labeled DNA.
