The osmotolerant yeast Zygosaccharomyces rouxii accumulates the polyols glycerol and D‐arabitol intracellularly in response to hyperosmotic stress, but the membrane transport proteins regulating polyol accumulation have not been studied. We have cloned and characterized a FPS1 homologue in Z. rouxii NRRL Y2547, and its sequence revealed a 2709 bp open reading frame encoding a peptide of 692 deduced amino acids with 56.9% identity to the Saccharomyces cerevisiae Fps1p. The role of this putative… Expand
Two glycerol uptake systems contribute to the high osmotolerance of Zygosaccharomyces rouxii
TLDR
Both transporters are highly important, though Z. rouxii’s CBS 732T cells do not use external glycerol as a source of carbon, though the two ZrSTL1 and Zr STL2 genes are not repressed by glucose, but their expression and activity are downregulated by fructose and upregulated by non‐fermentable carbon sources.

Osmoresistant yeast Zygosaccharomyces rouxii: the two most studied wild‐type strains (ATCC 2623 and ATCC 42981) differ in osmotolerance and glycerol metabolism
TLDR
Compared two wild‐type strains of Z. rouxii with regard to some of their morphological, physiological and genomic properties, the ATCC 42981 strain showed a higher resistance to salts, higher glycerol production and, unlike ATCC 2623, was able to assimilate Glycerol. Expand
Glycerol uptake and synthesis systems contribute to the osmotic tolerance of Kluyveromyces marxianus.
TLDR
Findings indicated that K. marxianus would increase glycerol synthesis by increasing GPD1 expression, increase Glycerol import from the extracellular environment by increasing STL1 expression and reduce glycerl efflux by reducing FPS1 expression under hyperosmotic stress. Expand
The Fps1p aquaglyceroporin facilitates the use of small aliphatic amides as a nitrogen source by amidase-expressing yeasts.
TLDR
Saccharomyces cerevisiae cannot grow on acetamide, but was conferred with an ability to use this and other small amides as nitrogen sources by heterologous expression of a Z. rouxii ORF with protein sequence identity to the amdS-encoded amidase of Aspergillus nidulans, an indication that these amides enter the cells of this yeast by passive diffusion through the Fps1p pore. Expand
Quantitative phenotypic analysis of multistress response in Zygosaccharomyces rouxii complex.
TLDR
The obtained phenotypic profiling contributes to provide quantitative insights for elucidating the adaptive mechanisms to stress in halo- and osmo-tolerant Zygosaccharomyces yeasts, which could imply different adaptation mechanisms to sugar- and salt-rich niches. Expand
Novel stress responses facilitate Saccharomyces cerevisiae growth in the presence of the monocarboxylate preservatives
TLDR
Mechanisms of weak acid resistance are found in Zygosaccharomyces, including a capacity for the oxidative degradation of sorbic and benzoic acids conferred by a mitochondrial monooxygenase, a system absent in S. cerevisiae. Expand
Overexpression of Saccharomyces cerevisiae mannitol dehydrogenase gene (YEL070w) in glycerol synthesis-deficient S. Cerevisiae mutant
TLDR
Six highly homologous peptide motifs were identified in the amino acid sequence of the YEL070w product by comparison with those of microbial MDH proteins, revealing a typical coenzyme-binding site and an active site that are specific to enzymes participating in the dehydrogenation of alcohols groups. Expand
A permease encoded by STL1 is required for active glycerol uptake by Candida albicans.
TLDR
It is concluded that a plasma-membrane H(+) symporter encoded by C. albicans Glycerol uptake protein(s) actively transports glycerol into C.Albicans cells. Expand
Adaptive response and tolerance to sugar and salt stress in the food yeast Zygosaccharomyces rouxii.
TLDR
This review summarizes recent insights on the mechanisms used by Z. rouxii and other osmo and halotolerant food yeasts to endure salts and sugars stresses and suggests how an integrated and system-based knowledge on these mechanisms may impact food and biotechnological industries. Expand
Use of In Vivo 13C Nuclear Magnetic Resonance Spectroscopy To Elucidate l-Arabinose Metabolism in Yeasts
TLDR
This report provides the first experimental evidence for a link between l-arabinose metabolism in fungi and the oxidative branch of the PPP and suggests rational guidelines for the design of strategies for the production of new and efficient l-Arabinose-fermenting yeasts. Expand

Fps1p controls the accumulation and release of the compatible solute glycerol in yeast osmoregulation
TLDR
It is demonstrated that yeast cells control glycerol accumulation in part via a regulated, Fps1p‐mediated export of glyceroled, which seems to be independent of the known yeast osmosensing HOG and PKC signalling pathways. Expand
Implications of FPS1 deletion and membrane ergosterol content for glycerol efflux from Saccharomyces cerevisiae.
TLDR
Ergosterol supplementation was shown to partially suppress the hypo-osmotic sensitivity phenotype of the fps1delta strain, leading to more efficient glycerol efflux, and improved survival, and the results obtained suggest that a higher ergosterol content facilitates the flux of Glycerol across the plasma membrane of S. cerevisiae cells. Expand
GUP1 and its close homologue GUP2, encoding multimembrane‐spanning proteins involved in active glycerol uptake in Saccharomyces cerevisiae
TLDR
The identification of YGL084c, encoding a multimembrane‐spanning protein, as being essential for proton symport of glycerol into S. cerevisiae is presented, the first report on a gene product involved in active transport of Glycerol in yeasts. Expand
A Short Regulatory Domain Restricts Glycerol Transport through Yeast Fps1p*
TLDR
Intragenic second-site suppressor mutations of the sensitivity to high osmolarity conferred by truncation of the regulatory domain caused diminished glycerol transport, confirming that elevated channel activity is the cause of the osmosensitive phenotype. Expand
Characteristics of Fps1-dependent and -independent glycerol transport in Saccharomyces cerevisiae
TLDR
The results indicate the presence of an Fps1p-dependent facilitated diffusion system in glucose-grown cells and an FPS1 p-independent proton symport system in derepressed cells. Expand
Fps1, a yeast member of the MIP family of channel proteins, is a facilitator for glycerol uptake and efflux and is inactive under osmotic stress.
TLDR
It is shown that overexpression of FPS1 enhances glycerol production and is concluded that Fps1 is a regulated yeast Glycerol facilitator controlling glycerl production and cytosolic concentration, and might have additional functions. Expand
A Regulatory Domain in the C-terminal Extension of the Yeast Glycerol Channel Fps1p*
TLDR
The results show that the C-terminal extension is also involved in restricting transport through Fps1p, and a sequence of 12 amino acids is identified close to the sixth transmembrane domain that seems to be important for controlling FPS1p function. Expand
The two isoenzymes for yeast NAD+‐dependent glycerol 3‐phosphate dehydrogenase encoded by GPD1 and GPD2 have distinct roles in osmoadaptation and redox regulation
TLDR
It is concluded that expression of GPD2 is controlled by a novel, oxygen‐independent, signalling pathway which is required to regulate metabolism under anoxic conditions. Expand
Analysis of the Pore of the Unusual Major Intrinsic Protein Channel, Yeast Fps1p*
TLDR
It is observed that mutations made in Fps1p to “restore” the signature NPA motifs did not substantially affect channel function, and that the different pore structures of FPS1p and GlpF may reflect the physiological roles of the two glycerol facilitators. Expand
