RESULTS suc2 gene fragment of about 1.5 kb was amplified and cloned. DNA sequencing confirmed that , compared with the published sequence, the cloned suc2 gene had correct sequ ence except for one point mutation, but that did not alter the amino acid sequence o f t he encoded peptide. By transformation of yeast cells with a constructed gene dis ruption vector, four yeast clones were obtained which showed correct auxotrophy. PCR and DNA sequencing indicated that these yeast clones had the expected genot ype.
