title: Molecular cloning and sequence analysis of a mannitol dehydrogenase gene and isolation of mdh promoter from Candida magnoliae.
abstract: The mdh gene encodes mannitol dehydrogenase (MDH), which catalyzes the conversion of fructose into mannitol. The putative mdh gene of Candida magnoliae was isolated by PCR using the primers deduced from the N-terminal amino acid sequences of an intact MDH and its tryptic peptides, cloned in E. coli, and sequenced. The mdh gene consisted of 852 bp encoding for 283 amino acids. Analysis of the amino acid sequence revealed that MDH consisted of typical NADPH-dependent short chain dehydrogenases/reductases (SDRs). To develop a strong promoter to induce expression of the foreign genes in C. magnolia, the putative promoter was isolated. The reporter protein, GFP, was well-expressed under the control of the putative mdh promoter of 153 bp in C. magnoliae.
