Isolation and characterisation of the linked genes, FPS1 and QCR8, coding for farnesyl-diphosphate synthase and the 11 kDa subunit VIII of the mitochondrial bc1-complex in the yeast Kluyveromyces lactis.

The KlQCR8 gene of the yeast Kluyveromyces lactis encoding subunit VIII of the mitochondrial bc1 complex is 70.2% identical to its counterpart in Saccharomyces cerevisiae (ScQCR8). As in S. cerevisiae, chromosomal linkage between the K. lactis QCR8 and FPS1 genes is conserved, the two genes being separated by only 292 bp. Disruption of the KlQCR8 gene results in a respiratory-deficient phenotype. Compared with S. cerevisiae, expression of the KlQCR8 gene in glucose-grown cells is relatively high, yet is significantly induced when the cells are grown on non-fermentable carbon sources. The QCR8 promoters regions of the two yeasts lack overall DNA sequence similarity, but share DNA-binding sites for the transcription factors ABF1, CPF1 and HAP2/3/4. Deletion from the KlQCR8 promoter of a 93 bp region containing these sites significantly lowers mRNA levels during growth on either glucose or ethanol/glycerol, with a consequent reduction of growth rate on ethanol/glycerol.[1]
