Identification and Characterization of a Gene Encoding an ABC Transporter Expressed in the Dicarboxylic Acid-Producing Yeast Candida maltosa

抄録

A gene, CmCDR1, encoding an ABC transporter of the dicarboxylic acid (DCA)-producing yeast Candida maltosa was cloned. Transcription of CmCDR1 was upregulated in a DCA-hyper-producing mutant of C. maltosa in a later phase of culture on n-dodecane, but not in its parental strain. CmCDR1 expression was significantly induced by the longer-chain DCA in this mutant.
