Abstract
We cloned a genomic DNA fragment of the yeast Torulaspora delbrueckii by complementation of a Saccharomyces cerevisiae snf1Δ mutant strain. DNA sequence analysis revealed that the fragment contained a complete open reading frame (ORF), which shares a high similarity with the S. cerevisiae energy sensor protein kinase Snf1. The cloned TdSNF1 gene was able to restore growth of the S. cerevisiae snf1Δ mutant strain on media containing nonfermentable carbon sources. Furthermore, cells of the Tdsnf1Δ mutant were unable to proliferate under nonfermenting conditions. Finally, protein domain analysis showed that TdSnf1p contains a typical catalytic protein kinase domain (positions 41-293), which is also present in other Snf1p homologues. Within this region we identified a protein kinase ATP-binding region (positions 48-71) and a consensus Ser/Thr protein kinase active site (positions 160-172).
