Fig. 1From: Engineering an efficient and tight d-amino acid-inducible gene expression system in Rhodosporidium/Rhodotorula speciesReactions catalyzed by d-amino acid oxidase. Imino acid is believed be hydrolyzed non-enzymatically to the corresponding keto acid and ammonia. l-amino acids may be converted to d-amino acids by l-amino acid racemaseBack to article page
