RAG4 gene encodes a glucose sensor in Kluyveromyces lactis.
The rag4 mutant of Kluyveromyces lactis was previously isolated as a fermentation-deficient mutant, in which transcription of the major glucose transporter gene RAG1 was affected. The wild-type RAG4 was cloned by complementation of the rag4 mutation and found to encode a protein homologous to Snf3 and Rgt2 of Saccharomyces cerevisiae. These two proteins are thought to be sensors of low and high...
متن کاملA single-copy gene encodes Kex1, a serine endoprotease of Pneumocystis jiroveci.
We have cloned and characterized the kex1 gene of Pneumocystis jiroveci. Unlike the case for Pneumocystis carinii, in which the homologous PRT-1 genes are multicopy, kex1 is a single-copy gene encoding a protein homologous to fungal serine endoproteases, which localize to the Golgi apparatus. Thus, substantial biological differences can be seen among Pneumocystis species.
متن کاملMating type switching and transcriptional silencing in Kluyveromyces lactis
To explore the similarities and differences of regulatory circuits among budding yeasts, we characterized the role of unscheduled meiotic gene expression 6 (UME6) and a novel mating type switching pathway in Kluyveromyces lactis. We found that Ume6 was required for transcriptional silencing of the cryptic mating-type loci HML and HMRa. Ume6 acted directly at these loci by binding to the cis-re...
متن کاملInsight into the Kluyveromyces lactis Pdr1p regulon.
The overexpression of efflux pumps is an important mechanism leading to the development of multidrug resistance phenomenon. The transcription factor KlPdr1p, belonging to the Zn2Cys6 family, is a central regulator of efflux pump expression in Kluyveromyces lactis. To better understand how KlPDR1-mediated drug resistance is achieved in K. lactis, we used DNA microarrays to identify genes whose e...
متن کاملThe KlGpa1 Gene Encodes a G-Protein a Subunit That Is a Positive Control Element in the Mating Pathway of the Budding Yeast Kluyveromyces lactis
The cloning of the gene encoding the KlGpa1p subunit was achieved by standard PCR techniques and by screening a Kluyveromyces lactis genomic library using the PCR product as a probe. The full-length open reading frame spans 1,344 nucleotides including the stop codon. The deduced primary structure of the protein (447 amino acid residues) strongly resembles that of Gpa1p, the G-protein a subunit ...
