Yeast producing alcohol dehydrogenase 1 (YADH 1) enzyme has been used as a biocatalyst for the synthesis of an optically active flavouring compound known as citronellol. However, the slow growth of yeast (Saccharomyces cerevisiae) has deterred the progress of biotransformation. The main purpose of this work is to clone the genes producing YADH1 enzyme from yeast into a faster growing bacteria, Escherichia coli. Initially, the sequence of the gene encoding this protein has been identified in the S. cerevisiae Genome Databases (SGD). The so-called Yadh1 gene sequence is located from coordinate 159548 to 160594 on chromosome XV of yeast. Based on this information, two primer sequences (Forward and Reverse) were constructed. Each of these primers will bind to either end of the Yadh1 gene. The Yadh1 gene was then amplified using Polymerase Chain Reaction (PCR) technique. The amplified Yadh 1 gene was successfully cloned into a cloning vector, TOPO TA plasmid. This plasmid also contains a gene which confers resistance to ampicillin. This recombinant plasmid was then inserted into Escherichia coli TOP 10 using heat shock protocol at 42oC. Finally, the cloned bacteria containing the recombinant TOPO TA plasmid harbouring Yadh1 gene was able to grow on Luria Bertani (LB) media supplied with antibiotic.
