Mating pheromones of Saccharomyces kluyveri: pheromone interactions between Saccharomyces kluyveri and Saccharomyces cerevisiae.

Saccharomyces kluyveri is a heterothallic yeast with two allelic mating types denoted as a-k and alpha-k by analogy with Saccharomyces cerevisiae and from the work described here. S. kluyveri produces mating pheromones analogous to those of S. cerevisiae, but which appear to have different specificity. S. kluyveri thus differs from S. cerevisiae, Hansenula wingei, and Schizosaccharomyces pombe ...

Saccharomyces kluyveri Fungemia in an Infant with Severe Combined Immunodeficiency.

A 5-month-old boy presented to us with fever and cough for 15 days and one episode of generalized tonic clonic convulsion. He had oral thrush at 1 month and otitis media at 2 months of age. Birth weight was 2.9 kg. His elder brother died at 11 months of age due to some respiratory illness. On presentation, he was lethargic, and had tachycardia and tachypnea. He had oral thrush, diffuse greyish ...

Pheromones and pheromone receptors are the primary determinants of mating specificity in the yeast Saccharomyces cerevisiae.

Saccharomyces cerevisiae has two haploid cell types, a and alpha, each of which produces a unique set of proteins that participate in the mating process. We sought to determine the minimum set of proteins that must be expressed to allow mating and to confer specificity. We show that the capacity to synthesize alpha-factor pheromone and a-factor receptor is sufficient to allow mating by mat alph...

Biogenesis of the Saccharomyces cerevisiae Mating Pheromone a-Factor

The Saccharomyces cerevisiae mating pheromone a-factor is a prenylated and carboxyl methylated extracellular peptide signaling molecule. Biogenesis of the a-factor precursor proceeds via a distinctive multistep pathway that involves COOH-terminal modification. NH2-terminal proteolysis, and a nonclassical export mechanism. In this study, we examine the formation and fate of a-factor biosynthetic...

Saccharomyces kluyveri FAD3 encodes an v3 fatty acid desaturase

Received 22 January 2004 Revised 26 February 2004 Accepted 27 February 2004 Fungi, like plants, are capable of producing the 18-carbon polyunsaturated fatty acids linoleic acid and a-linolenic acid. These fatty acids are synthesized by catalytic reactions of D12 and v3 fatty acid desaturases. This paper describes the first cloning and functional characterization of a yeast v3 fatty acid desatur...
