TY - JOUR. T1 - Structure and function of glycosylated tandem repeats from Candida albicans als adhesins. AU - Frank, Aaron T.. AU - Ramsook, Caleen B.. AU - Otoo, Henry N.. AU - Tan, Cho. AU - Soybelman, Gregory. AU - Rauceo, Jason M.. AU - Gaur, Nand K.. AU - Klotz, Stephen A.. AU - Lipke, Peter N.. PY - 2010/3. Y1 - 2010/3. N2 - Tandem repeat (TR) regions are common in yeast adhesins, but their structures are unknown, and their activities are poorly understood. TR regions in Candida albicans Als proteins are conserved glycosylated 36-residue sequences with cell-cell aggregation activity (J. M. Rauceo, R. De Armond, H. Otoo, P. C. Kahn, S. A. Klotz, N. K. Gaur, and P. N. Lipke, Eukaryot. Cell 5:1664-1673, 2006). Ab initio modeling with either Rosetta or LINUS generated consistent structures of three-stranded antiparallel β-sheet domains, whereas randomly shuffled sequences with the same composition generated various structures with consistently higher energies.

In immunolocalization experiments, we previously had shown that Cdc42p was not observed around the plasma or internal membranes and was only variably seen at the mother-bud neck region (43). The disparity between these patterns and GFP-Cdc42p targeting patterns described herein may be due to the nature of the anti-Cdc42p antibody used. The antibody was raised against a peptide sequence containing amino acids 165 to 181, a region adjacent to the membrane-targeting domain (42) and likely to be in close proximity to the plasma membrane, raising the possibility that steric hindrance interfered with efficient binding. An underestimation of Cdc42p membrane targeting may also be due to the immunolocalization protocol used, including the use of cell wall-digesting enzymes and sodium dodecyl sulfate, required for efficient Cdc42p visualization. These possibilities were supported by the observation that the GFP-Cdc42p immunolocalization pattern with anti-Cdc42p antibody was similar to that seen previously ...
TY - JOUR. T1 - Mechanisms of protein adhesion on surface films of hydrophobin. AU - Wang, Zefang. AU - Lienemann, Michael. AU - Qiau, Mingqiang. AU - Linder, Markus. PY - 2010/5/3. Y1 - 2010/5/3. N2 - Hydrophobins are adhesive proteins produced by filamentous fungi. They are in many cases secreted into the medium and adsorb readily to a number of different surfaces. They fulfill many different tasks such as the formation of various coatings and mediating adhesion of fungi to surfaces. The mechanism of how hydrophobins adhere and how they mediate fungal adhesion is of interest both from the point of view of fungal biology and for various biotechnical immobilization applications. It has been shown that hydrophobins typically form a monomolecular layer on solid substrates. We are especially interested in how a surface layer of hydrophobin can mediate the adhesion of a second layer of another protein. In this work we systematically studied how proteins adsorb onto hydrophobins that are bound as ...

During the extreme polarized growth of fungal hyphae, secretory vesicles are thought to accumulate in a subapical region called the Spitzenkörper. The human fungal pathogen Candida albicans can grow in a budding yeast or hyphal form. When it grows as hyphae, Mlc1 accumulates in a subapical spot suggestive of a Spitzenkörper-like structure, while the polarisome components Spa2 and Bud6 localize to a surface crescent. Here we show that the vesicle-associated protein Sec4 also localizes to a spot, confirming that secretory vesicles accumulate in the putative C. albicans Spitzenkörper. In contrast, exocyst components localize to a surface crescent. Using a combination of fluorescence recovery after photobleaching (FRAP) and fluorescence loss in photobleaching (FLIP) experiments and cytochalasin A to disrupt actin cables, we showed that Spitzenkörper-located proteins are highly dynamic. In contrast, exocyst and polarisome components are stably located at the cell surface. It is thought that in
TY - JOUR. T1 - Saccharomyces cerevisiae proteins involved in hybrid DNA formation in vitro. AU - Heyer, W. D.. AU - Johnson, A. W.. AU - Norris, D. N.. AU - Tishkoff, D.. AU - Kolodner, R. D.. PY - 1991. Y1 - 1991. N2 - RecA-like activities that can form hybrid DNA in vitro have been identified in a wide variety of organisms. We have previously described the strand exchange protein 1 (SEP1) from the yeast Saccharomyces cerevisiae that can form hybrid DNA in vitro. Purified as an Mr 132 000 polypeptide, recent molecular and immunological studies have now shown that the native form is an Mr 175 000 polypeptide containing strand exchange activity. The gene encoding SEP1 has been cloned and sequenced. The primary sequence failed to reveal any significant sequence homology to other sequences in data base searches. In vivo SEP1 was found to be essential for normal meiosis as cells containing a homozygous insertion mutation in the SEP1 gene failed to sporulate. In order to identify additional factors ...

TY - JOUR. T1 - Hydrophobins from Aspergillus species cannot be clearly divided into two classes. AU - Jensen,Britt Guillaume. AU - Andersen,Mikael Rørdam. AU - Pedersen,Mona Højgaard. AU - Frisvad,Jens Christian. AU - Søndergaard,Ib. PY - 2010. Y1 - 2010. N2 - Background Hydrophobins are a family of small secreted proteins with a characteristic pattern of eight cysteine residues found exclusively in filamentous fungi. They have originally been divided into two classes based on their physical properties and hydropathy patterns, and are involved in the attachment of hyphae to hydrophobic structures, the formation of aerial structures and appear to be involved in pathogenicity. Findings Analysis of nine genome sequences from seven Aspergilli revealed fifty hydrophobins, where each species displayed between two to eight hydrophobins. Twenty of the identified hydrophobins have not previously been described from these species. Apart from the cysteines, very little amino acid sequence homology was ...
Recent sequencing and assembly of the genome for the fungal pathogen Candida albicans used simple automated procedures for the identification of putative genes. We have reviewed the entire assembly, both by hand and with additional bioinformatic resources, to accurately map and describe 6,354 genes and to identify 246 genes whose original database entries contained sequencing errors (or possibly mutations) that affect their reading frame. Comparison with other fungal genomes permitted the identification of numerous fungus-specific genes that might be targeted for antifungal therapy. We also observed that, compared to other fungi, the protein-coding sequences in the C. albicans genome are especially rich in short sequence repeats. Finally, our improved annotation permitted a detailed analysis of several multigene families, and comparative genomic studies showed that C. albicans has a far greater catabolic range, encoding respiratory Complex 1, several novel oxidoreductases and ketone body degrading

A central theme in biology is to understand how different signaling outputs can be accomplished by changes to signal transduction pathways. Here, we examined epigenetic differences between two cell states in the human fungal pathogen Candida albicans. We show that cells in the white state are sterile due to multiple bottlenecks in MAPK signaling relative to mating-competent opaque cells. Alleviation of these bottlenecks by reverse engineering effectively converts sterile white cells into sexually competent cells. These results have broad implications for understanding how epigenetic changes can impact MAPK expression and signaling output, including events associated with tumorigenesis. We also propose a model for how the white-opaque switch gained control of sexual reproduction in Candida during evolution.. ...
I reveal that Saccharomyces cerevisiae Rtt109p promotes genome stability and resistance to DNA-damaging agents, and that it does this by functionally cooperating with the histone chaperone Asf1p to maintain normal chromatin structure. Furthermore, I show that, as for Asf1p, Rtt109p is required for histone H3 acetylation on lysine 56 (K56) in vivo. Moreover I show that Rtt109p directly catalyzes this modification in vitro in a manner that is stimulated by Asf1p. These data establish Rtt109p as a member of a new class of histone acetyltransferases and show that its actions are critical fro cell survival in the presence of DNA damage during S phase. In the second part of this thesis, I reveal that cells deleted for Saccharomyces cerevisiae ESC2 exhibit synthetic sickness when combined with deletions of many genes involved in maintaining genomic stability. Moreover, I show that esc2Δ mutant cells exhibit increased recombination frequency and increased relocalisation of recombination repair protein ...

To determine whether the C. albicans MTL gene cluster was required for the a1/α2-like repression activity, theGFP reporters were transformed into MTLa1deletion strains and evaluated for fluorescence. In contrast to the wild-type C. albicans strains, the MTLa1 mutant strains showed the same levels of fluorescence for all of the reporter constructs, indicating that the MTLa1 gene is required for the transcriptional repression activity (Fig. 4). Similar behavior was seen for both the complete deletion of the MTLa1 gene and for the MTLa1 homeodomain deletion, consistent with the DNA-binding domain of a1 being required for the repression activity (9). Northern (RNA) analysis also showed that transcription from the reporter constructs containing the functional hsg operators was derepressed in the MTLa1deletion mutants compared with the wild-type strain; however, in the absence of a1, the functional hsg operators still showed a slight amount of repression when compared with the mutated hsg operators ...

Saccharomyces cerevisiae is a species of budding yeast. It is perhaps the most useful yeast owing to its use since ancient times in baking and brewing. It is believed that it was originally isolated from the skins of grapes (one can see the yeast as a component of the thin white film on the skins of some dark-colored fruits such as plums; it exists among the waxes of the cuticle). It is one of the most intensively studied eukaryotic model organisms in molecular and cell biology, much like Escherichia coli as the model prokaryote. It is the microorganism behind the most common type of fermentation. Saccharomyces cerevisiae cells are round to ovoid, 5-10 micrometres in diameter. It reproduces by a division process known as budding. It is useful in studying the cell cycle because it is easy to culture, but, as a eukaryote, it shares the complex internal cell structure of plants and animals. S. cerevisiae was the first eukaryotic genome that was completely sequenced. The yeast genome database [1] is ...

TY - JOUR. T1 - Dynamic Effects Related to Steady-State Multiplicity in Continous Saccharomyces Cerevisiae Cultivations. AU - Lei, Frede. AU - Olsson, Lisbeth. AU - Jørgensen, Sten Bay. PY - 2004. Y1 - 2004. N2 - The behavioral differences between chemostat and productostat cultivation of aerobic glucose-limited Saccharomyces cerevisiae were investigated. Three types of experiments were conducted: a chemostat, where the dilution rate was shifted up or down in stepwise manner; and a productostat, with either stepwise changed or a rampwise increased ethanol setpoint, i.e., an accelero-productostat. The transient responses from chemostat and productostat experiments were interpreted using a simple metabolic flux model. In a productostat it was possible to obtain oxido-reductive steady states at dilution rates far below D-crit due to a strong repression of the respiratory system. However, these steady states could not be obtained in a chemostat, since a dilution rate shift-down from an ...

TY - JOUR. T1 - The transcriptional response to alkaline pH in Saccharomyces cerevisiae: Evidence for calcium-mediated signalling. AU - Serrano, Raquel. AU - Ruiz, Amparo. AU - Bernal, Dolores. AU - Chambers, James R.. AU - Ariño, Joaquín. PY - 2002/12/1. Y1 - 2002/12/1. N2 - The short-time transcriptional response of yeast cells to a mild increase in external pH (7.6) has been investigated using DNA microarrays. A total of 150 genes increased their mRNA level at least twofold within 45 min. Alkalinization resulted in the repression of 232 genes. The response of four upregulated genes, ENA1 (encoding a Na+-ATPase also induced by saline stress) and PHO84, PHO89 and PHO12 (encoding genes upregulated by phosphate starvation), was characterized further. The alkaline response of ENA1 was not affected by mutation of relevant genes involved in osmotic or oxidative signalling, but was decreased in calcineurin and rim101 mutants. Mapping of the ENA1 promoter revealed two pH-responsive regions. The ...
