Abstract
Saccharomyces cerevisiae (S. cerevisiae)invertase is encoded by a family of closely related SUC genes. To identify and understand the molecular basis for differences in substrate specificity, we examined 29 SUC alleles from industrialS. cerevisiaestrains and cloned alleles with small sequence differences into an invertase-negative strain. Our study showed that an F102Y substitution in Suc-enzymes lowers yeast invertase activity toward fructo-oligosaccharides (FOS) by 36% and the specificity factor by 43%. By contrast, an A409P substitution in Suc-enzymes resulted in an increased capacity of the yeast to hydrolyze FOS and Fibruline by 17 and 41%, respectively, likely because of a change in the loop conformation resulting in a wider active site. Bread dough fermentation experiments revealed that sucrose and fructan hydrolysis during fermentation is influenced by this natural variation in SUC sequences. Our research thus opens the door for the selection or engineering of yeasts and Suc-enzymes with specific activities that may ultimately allow controlling fructan hydrolysis.

Abstract
Previous studies in the yeast Saccharomyces cerevisiae have proposed a vacuolar localization for Ath1, which is difficult to reconcile with its ability to hydrolyze exogenous trehalose. We used fluorescent microscopy to show that the red fluorescent protein mCherry fused to the C-terminus of Ath1, although mostly localized in the vacuole, was also targeted to the cell surface. Also, hybrid Ath1 truncates fused at their C-terminus with the yeast internal invertase revealed that a 131 amino acid N-terminal fragment of Ath1was sufficient to target the fusion protein to the cell surface, enabling growth of the suc2Delta mutant on sucrose. The unique transmembrane domain appeared to be indispensable for the production of a functional Ath1, and its removal abrogated invertase secretion and growth on sucrose. Finally, the physiological significance of the cell-surface localization of Ath1 was established by showing that fusion of the signal peptide of invertase to N-terminal truncated Ath1 allowed the ath1Delta mutant to grow on trehalose, whereas the signal sequence of the vacuolar-targeted Pep4 constrained Ath1 in the vacuole and prevented growth of this mutant on trehalose. Use of trafficking mutants that impaired Ath1 delivery to the vacuole abrogated neither its activity nor its growth on exogenous trehalose.

Abstract
To reveal differences between inhibitor-resistant Saccharomyces cerevisiae strains and their parental strain and to investigate the response of S. cerevisiae to furfural, phenol, and acetic acid, comparative lipidomics strategy was employed using an LC-ESI/MS(n) technique on four S. cerevisiae strains, which include an industrial strain (SC) and three tolerant strains screened by this laboratory by step adaptationa furfural-tolerant strain (SCF), a phenol-tolerant strain (SCP), and an acetic acid-tolerant strain (SCA). Lipidome data were then analyzed using wavelet transform-principal component analysis (WT-PCA). Results revealed that phosphatidylcholines (PCs), phosphatidylinositols (PIs), and phosphatidic acids (PAs) were biomarkers for discriminating SC from SCF, SCP, and SCA, respectively. PIs were believed to be extraordinarily important in all inhibitor-tolerant processes because they were the biomarkers responsible for the discrimination of all four different strains. Further analysis of the distribution of different hydrocarbon chains revealed that both the saturation and the length of the chains helped in maintaining proper fluidity of membranes.

Abstract
Although enolase, other glycolytic enzymes, and a variety of cytoplasmic proteins lacking an N-terminal secretion signal have been widely described as located at the cell surface in yeast and in mammalian cells, their presence in this external location is still controversial. Here, we report that different experimental approaches (genetics, cellular biology and proteomics) show that yeast enolase can reach the cell surface and describe the protein regions involved in its cell surface targeting. Hybrid enolase truncates, fused at their C terminus with the yeast internal invertase or green fluorescent protein (GFP) as reporter proteins, proved that the 169 N-terminal amino acids are sufficient to target the protein to the cell surface. Furthermore, the enolase-GFP fusion co-localized with a plasma membrane marker. Enolase was also identified among membrane proteins obtained by a purification protocol that includes sodium carbonate to prevent cytoplasmic contamination. These proteins were analyzed by SDS-PAGE, trypsin digestion and LC-MS/MS for peptide identification. Elongation factors, mitochondrial membrane proteins and a mannosyltransferase involved in cell wall mannan biosynthesis were also identified in this fraction.

Abstract
Expression of HXT1, a gene encoding a Saccharomyces cerevisiae low-affinity glucose transporter, is regulated by glucose availability, being activated in the presence of glucose and inhibited when the levels of the sugar are scarce. In this study we show that 14-3-3 proteins are involved in the regulation of the expression of HXT1 by glucose. We also demonstrate that 14-3-3 proteins, in complex with Reg1, a regulatory subunit of Glc7 protein phosphatase, interact physically with Grr1 (a component of the SCF-Grr1 ubiquitination complex), a key player in the process of HXT1 induction by glucose. In addition, we show that the TOR kinase pathway participates actively in the induction of HXT1 expression by glucose. Inhibition of the TOR kinase pathway by rapamycin treatment abolishes HXT1 glucose induction. A possible involvement of PP2A protein phosphatase complex, through the Cdc55 B-subunit, in the glucose induction of HXT1 is also discussed.

Abstract
In all living organisms, secreted proteins play essential roles in different processes. Of special interest is the construction of the fungal cell wall, since this structure is absent from mammalian cells. The identification of the proteins involved in its biogenesis is therefore a primary goal in antifungal research. To perform a systematic identification of such proteins in Candida albicans, we carried out a genetic screening in which in-frame fusions with an intracellular allele of invertase gene SUC2 of Saccharomyces cerevisiae can be used to select and identify putatively exported proteins in the heterologous host S. cerevisiae. Eighty-three clones were selected, including 11 previously identified genes from C. albicans as well as 41 C. albicans genes that encode proteins homologous to already described proteins from related organisms. They include enzymes involved in cell wall synthesis and protein secretion. We also found membrane receptors and transporters presumably related to the interaction of C. albicans with the environment as well as extracellular enzymes and proteins involved in different morphological transitions. In addition, 11 C. albicans open reading frames (ORFs) identified in this screening encode proteins homologous to unknown or putative proteins, while 5 ORFs encode novel secreted proteins without known homologues in other organisms. This screening procedure therefore not only identifies a set of targets of interest in antifungal research but also provides new clues for understanding the topological locations of many proteins involved in processes relevant to the pathogenicity of this microorganism.

Abstract
2-deoxyglucose (2-DOG), a non-metabolize analogue of glucose, is taken up by yeast using the same transporter(s) as glucose and is phosphorylated by hexokinases producing 2-deoxyglucose-6-P. We found that in DOGR yeasts, 2-DOG was not able to trigger glucose repression, even at concentrations of 0.5%. This result suggests that the specific 2-DOG-6P phosphatase, the enzyme responsible for the DOGR phenotype, may be involved in inhibiting the process of catabolite repression mediated by 2-DOG.

Abstract
Non-coding nucleotide sequences located 5' upstream of the transcriptional start site play an essential role in gene expression as they contain binding sites for transcription and regulatory factors. The yeast SUC gene family is a useful model to study the influence that nucleotide exchanges within the promoter regions have on their expression, since (i) these genes, regulated by glucose repression, are differentially transcribed (invertase activity produced by distinct SUC genes may show variations of about 10-fold); and (ii) promoter sequences of SUC3, SUC4, SUC5 and SUC7 are more than 99% homologous, showing only six base exchanges among all of them. Comparison of these nucleotide exchanges with the expression of each SUC gene (located either on chromosomes or on multicopy and centromeric plasmids) points out that naturally occurring base exchanges as few as one nucleotide modification (G to A transition at position -497 relative to the translational start site, C to T transition at position -460 and insertion/deletion of a T at positions -590, -586 and -435) may have a strong effect on gene expression.
