Abstract
Flor yeasts confer a wide range of organoleptic properties to Sherry-type wines during a process called "biological aging" that takes place after alcoholic fermentation. These kinds of yeasts adapt to a biological aging condition by forming a biofilm known as "flor velum" and by changing from fermentative to oxidative metabolism. It has been reported that some functions such as increase of cell surface hydrophobicity or changes to lipid metabolism are enhanced when yeasts switch to biofilm lifestyle. Here, we attempt to reveal intracellular metabolites and protein molecular functions not documented before that are relevant in biofilm formation and in fermentation by an endometabolome and proteome screening. We report that at early stages of biofilm formation, flor yeasts accumulate mannose, trehalose, glycerol, oleic and stearic acids and synthesize high amounts of GTPases, glycosylases and lipoproteins. On the other hand, in early fermentation, flor yeasts rapidly consume glucose and phosphoric acid; and produce abundant proteins related to chromatin binding, transcription factors and methyl transferases.

Abstract
Biomass resources are attractive carbon sources for bioproduction because of their sustainability. Many studies have been performed using biomass resources to produce sugars as carbon sources for cell factories. Expression of biomass hydrolyzing enzymes in cell factories is an important approach for constructing biomass-utilizing bioprocesses because external addition of these enzymes is expensive. In particular, yeasts have been extensively engineered to be cell factories that directly utilize biomass because of their manageable responses to many genetic engineering tools, such as gene expression, deletion and editing. Biomass utilizing bioprocesses have also been developed using these genetic engineering tools to construct metabolic pathways. However, sugar input and product output from these cells are critical factors for improving bioproduction along with biomass utilization and metabolic pathways. Transporters are key components for efficient input and output activities. In this review, we focus on transporter engineering in yeast to enhance bioproduction from biomass resources.

Abstract
The yeast Saccharomyces cerevisiae employs multiple pathways to coordinate sugar availability and metabolism. Glucose and other sugars are detected by a G protein-coupled receptor, Gpr1, as well as a pair of transporter-like proteins, Rgt2 and Snf3. When glucose is limiting, however, an ATP-driven proton pump (Pma1) is inactivated, leading to a marked decrease in cytoplasmic pH. Here we determine the relative contribution of the two sugar-sensing pathways to pH regulation. Whereas cytoplasmic pH is strongly dependent on glucose abundance and is regulated by both glucose-sensing pathways, ATP is largely unaffected and therefore cannot account for the changes in Pma1 activity. These data suggest that the pH is a second messenger of the glucose-sensing pathways. We show further that different sugars differ in their ability to control cellular acidification, in the manner of inverse agonists. We conclude that the sugar-sensing pathways act via Pma1 to invoke coordinated changes in cellular pH and metabolism. More broadly, our findings support the emerging view that cellular systems have evolved the use of pH signals as a means of adapting to environmental stresses such as those caused by hypoxia, ischemia, and diabetes.

Abstract
Transcription of SUC2, the gene that encodes the cytoplasmic and secreted forms of the enzyme invertase, is controlled by glucose repression and derepression mechanisms in Saccharomyces cerevisiae. Several regulatory factors such as the Mig1p-Tup1p-Ssn6p repressor complex and the Snf1p kinase complex have been identified previously as regulators of SUC2 expression. We show that, in addition to these factors, expression of SUC2 is affected by mutations in the gene GCR1 that encodes the glycolysis regulatory protein Gcr1p. Expression of Suc2-LacZ was not repressed by glucose in gcr1 mutant yeast cells exposed to glucose. Furthermore, secreted invertase activity was constitutively expressed under glucose-repressed and derepressed conditions in gcr1 mutants. DNA gel mobility shift assays and in-vitro DNase I protection experiments mapped a DNA binding site for Gcr1p in the transcriptional control region of the SUC2 gene, next to a previously mapped Mig1p binding site. However, the mechanism by which gcr1 mutations relieve glucose repression remains obscure.

Abstract
The Candida utilis yeast, which is cultivated in liquid media enriched with saccharose, synthesizes the well-known invertase of 300 kDa (EC 3.2.1.26). This enzyme is present both intracellularly in the periplasmic space and extracellularly in the culture broth. However, it was determined that the same C. utilis strain cultured in certain conditions is simultaneously capable of producing another, still unknown form of invertase with a molecular mass of 60 kDa. The presence of the latter enzymatic form was detected in cells as well as in the liquid culture medium. Both invertase forms were purified using a three-step process (ion-exchange chromatography, affinity chromatography, and preparative column electrophoresis) and named, due to their different migration ratio in polyacrylamide gel electrophoresis, F-form (Fast; 60 kDa) and S-form (Slow; 300 kDa). The F-form of invertase was found to be nonglycosylated as opposed to the well-known S-form of invertase from the same source. The physicochemical properties of the F-form of invertase (isoelectric point, substrate specificity, pH, and temperature optima) were determined and compared with those of the S-form of the enzyme.

Abstract
Synchronized Saccharomyces cerevisiae cell populations were used to examine secretion rates of a heterologous protein as a function of cell cycle position. The synchronization procedure had a profound effect on the type and quality of data obtained. When cell synchrony was induced by cell cycle-arresting drugs, a significant physiological perturbation of cells was observed that obscured representative secretion data. In contrast, synchronization with centrifugal elutriation resulted in synchronized first-generation daughter cells with undetectable perturbation of the physiological state. The synchronized cells did not secrete significant amounts of protein until they reached cell division, suggesting that the secretion process in these cells is strongly cell cycle dependent. However, the maximum secretion rate of the synchronized culture (7-14 molecules/cell/second) was significantly lower than that of an asynchronous culture (29-51 molecules/cell/second). This result indicates that young daughter cells isolated in the synchronization process exhibit different protein secretion behavior than older mother cells that are absent in the synchronized cell population but present in the asynchronous culture.

Abstract
Two ammonium-inducible, chloroplast-localized NADP-specific glutamate dehydrogenase isoenzymes were purified to homogeneity from Chlorella sorokiniana. These isoenzymes were homopolymers of either alpha- or beta-subunits with molecular weights of 55,500 or 53,000, respectively. The alpha-isoenzyme was preferentially induced at low ammonium concentrations (2 millimolar or lower), whereas only the beta-isoenzyme accumulated after cells were fully induced (120 minutes) at high ammonium concentrations (29 millimolar). Purification of isoenzymes was achieved by (NH(4))(2)SO(4) fractionation, gel-filtration, anion-exchange fast protein liquid chromatography, and affinity chromatography. The alpha- and beta-isoenzymes were separated by their differential binding to Type 4 nicotinamide adenine dinucleotide phosphate-Sepharose. Both isoenzymes bound to an antibody affinity column to which purified antibody (prepared against beta-isoenzyme) was covalently attached. Peptide mapping of the subunits showed them to have a high degree of sequence homology. Both subunits were synthesized in vitro from precursor protein(s) with a molecular weight of 58,500. Although the subunits have similar chemical, physical, and antigenic properties, their holoenzymes have strikingly different ammonium K(m) values. The ammonium K(m) of the beta-isoenzyme remained constant at approximately 75 millimolar, whereas this K(m) of the alpha-isoenzyme ranged from 0.02 to 3.5 millimolar, depending upon nicotinamide adenine dinucleotide phosphate concentration.

Abstract
A new method for detecting invertase activity in Saccharomyces cerevisiae colonies was used to screen for mutants resistant to catabolite repression of invertase. Mutations causing the highest level of derepression were located in two previously identified genes, cyc8 and tup1. Several of the cyc8 mutations, notably cyc8-10 and cyc8-11, were temperature dependent, repressed at 23 degrees C, and derepressed at 37 degrees C. The kinetics of derepression of invertase mRNA in cyc8-10 cells shifted from 23 to 37 degrees C was determined by Northern blots. Invertase mRNA was detectable at 5 min after the shift, with kinetics of accumulation very similar to that of wild-type cells shifted from high-glucose to low-glucose medium. Assays of representative enzymes showed that many but not all glucose-repressible enzymes are derepressed in both cyc8 and tup1 mutants. cyc8 and tup1 appear to be the major negative regulatory genes controlling catabolite repression in yeasts.

Abstract
All microbody proteins studies, including one microbody membrane protein, are made on free polysomes and imported post-translationally. This holds for animal tissues, plants, and fungi. The majority of microbody protein sub-units are synthesized in a form not detectably different from mature sub-units. In five cases a larger precursor protein has been found. The position of the extra piece in this precursor is not known. In two of the five cases, processing of the precursor is not coupled to import; in the other three this remains to be determined. It is not even known whether information in the prepiece contributes to topogenesis, or serves other purposes. Microbody preparations from Neurospora, plant tissue and rat liver can take up some newly synthesized microbody proteins in vitro. In most cases uptake is inefficient. No special requirements for uptake have been established and whether a receptor is involved is not yet known. Several examples have been reported of peroxisomal enzymes with a counterpart in another cell compartment. With the exception of catalase, no direct evidence is available in any of these cases for two isoenzymes specified by the same gene. In the Zellweger syndrome, a lethal hereditary disease of man, characterized by a lack of peroxisomes, the levels of several enzymes of lipid metabolism are strongly decreased. In contrast, D-amino-acid oxidase, L-alpha-hydroxyacid oxidase and catalase levels are normal. The catalase resides in the cytosol. Since there is no separate gene for cytosolic catalase, the normal catalase levels in Zellweger cells show that some peroxisomal enzymes can mature and survive stably in the cytosol. It is possible that maturation of the peroxisomal enzyme in the cytoplasm can account for the finding of cytosolic catalase in some normal mammalian cells. The glycosomes of trypanosomes are microbodies that contain a glycolytic system. Comparison of the glycosomal phosphoglycerate kinase with its cytosolic counterpart has shown that these isoenzymes are 93% homologous in amino-acid sequence, but less than 50% homologous to the corresponding enzymes of yeast and mammals. This implies that few alterations are required to direct a protein into microbodies. This interpretation is supported by the evidence for homology between some microbody and mitochondrial isoenzymes in other organisms mentioned under point 4. The major changes of the glycosomal phosphoglycerate kinase relative to the cytosolic enzyme are a large increase in positive charge and a C-terminal extension of 20 amino acids.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
Considerable advances have been made in recent years in our understanding of the biochemistry of protein and nucleic acid synthesis and, particularly, the molecular biology of gene expression in eukaryotes. The yeast Saccharomyces cerevisiae, and to a lesser extent Schizosaccharomyces pombe, has had a preeminent role as a focus for these studies, principally because of the facility with which these organisms can be experimentally manipulated biochemically and genetically. This review will be designed to critically examine and integrate recent advances in several vital areas of regulatory control of enzyme synthesis in yeast: structure and organization of DNA, transcriptional regulation, post-transcriptional modification, control of translation, post-translational modification and secretion, and cell-cycle modulation. It will attempt to emphasize and illustrate, where detailed information is available, principal underlying molecular mechanisms, and it will attempt to make relevant comparisons of this material to inferred and demonstrated facets of regulatory control of enzyme and protein synthesis in higher eukaryotes.

Abstract
When S. cerevisiae growing in the presence of glucose (repressive condition) was shifted to higher temperatures, invertase was secreted. This secretion required protein synthesis, but was independent of RNA formation (Mormeneo & Sentandreu 1982). In addition accumulation of invertasespecific messenger RNA occurred in the absence of protein synthesis but was expressed only after synthesis of protein. Invertase mRNA was continuously synthesized under repressive conditions and the levels of this mRNA were regulated by the presence of glucose. The hexose regulated the concentration of this mRNA at the level of transcription and/or by sensitization of this messenger RNA. The expression of the invertase mRNA present in the cells under repressive conditions was also regulated by glucose at the level of translation and/or secretion. As a result of these processes, under repressive conditions invertase is eliminated before secretion takes place.
