Heterogeneity in Mitochondrial Morphology and Membrane Potential Is Independent of the Nuclear Division Cycle in Multinucleate Fungal Cells
American Society for Microbiology - Tập 11 Số 3 - Trang 353-367 - 2012
John Gerstenberger, Patricia Occhipinti, Amy S. Gladfelter
ABSTRACT In the multinucleate filamentous fungus Ashbya gossypii , nuclei divide asynchronously in a common cytoplasm. We hypothesize that the division cycle machinery has a limited zone of influence in the cytoplasm to promote nuclear autonomy. Mito...... hiện toàn bộ
Independent Metalloregulation of Ace1 and Mac1 in Saccharomyces cerevisiae
American Society for Microbiology - Tập 4 Số 11 - Trang 1863-1871 - 2005
G A Keller, Amanda Bird, Dennis R. Winge
ABSTRACT Ace1 and Mac1 undergo reciprocal copper metalloregulation in yeast cells. Mac1 is functional as a transcriptional activator in copper-deficient cells, whereas Ace1 is a transcriptional activator in copper-replete cells. Cells undergoing a transition from copper-deficient to copper-sufficient conditions through a switch in the growth medium show a...... hiện toàn bộ
Saccharomyces cerevisiae Heat Shock Transcription Factor Regulates Cell Wall Remodeling in Response to Heat Shock
American Society for Microbiology - Tập 4 Số 6 - Trang 1050-1056 - 2005
Hiromi Imazu, Hiroshi Sakurai
ABSTRACT The heat shock transcription factor Hsf1 of the yeast Saccharomyces cerevisiae regulates expression of genes encoding heat shock proteins and a variety of other proteins as well. To better understand the cellular roles of Hsf1, we screened multicopy suppressor genes of a temperature-...... hiện toàn bộ
Role of Heat Shock Transcription Factor in Saccharomyces cerevisiae Oxidative Stress Response
American Society for Microbiology - Tập 6 Số 8 - Trang 1373-1379 - 2007
Ayako Yamamoto, Junko Ueda, Noritaka Yamamoto, Naoya Hashikawa, Hiroshi Sakurai
ABSTRACT The heat shock transcription factor Hsf1 of the yeast Saccharomyces cerevisiae regulates the transcription of a set of genes that contain heat shock elements (HSEs) in their promoters and function in diverse cellular processes, including protein folding. Here, we show that Hsf1 activ...... hiện toàn bộ
The Pre-mRNA Splicing Machinery of Trypanosomes: Complex or Simplified?
American Society for Microbiology - Tập 9 Số 8 - Trang 1159-1170 - 2010
Arthur Günzl
ABSTRACT Trypanosomatids are early-diverged, protistan parasites of which Trypanosoma brucei , Trypanosoma cruzi , and several species of ... hiện toàn bộ
Metabolic-Flux Profiling of the Yeasts Saccharomyces cerevisiae and Pichia stipitis
American Society for Microbiology - Tập 2 Số 1 - Trang 170-180 - 2003
Jocelyne Fiaux, Zeynep Petek Çakar, Marco Sonderegger, Kurt Wüthrich, Thomas Szyperski, Uwe Sauer
ABSTRACT The so far largely uncharacterized central carbon metabolism of the yeast Pichia stipitis was explored in batch and glucose-limited chemostat cultures using metabolic-flux ratio analysis by nuclear magnetic resonance. The concomitantly characterized network of active metabolic pathwa...... hiện toàn bộ
Genome Sequence of the Oleaginous Red Yeast Rhodosporidium toruloides MTCC 457
American Society for Microbiology - Tập 11 Số 8 - Trang 1083-1084 - 2012
Shailesh Kumar, Hariom Kushwaha, Anand Bachhawat, Gajendra P. S. Raghava, K. Ganesan
ABSTRACT We report the de novo assembled 20.05-Mb draft genome of the red yeast Rhodosporidium toruloides MTCC 457, predicted to encode 5,993 proteins, 4 rRNAs, and 125 tRNAs. Proteins known to be un...... hiện toàn bộ
Genome-Based Approaches to Understanding Phosphorus Deprivation Responses and PSR1 Control in Chlamydomonas reinhardtii
American Society for Microbiology - Tập 5 Số 1 - Trang 26-44 - 2006
Jeffrey L. Moseley, Chiung‐Wen Chang, Arthur Grossman
ABSTRACT The Chlamydomonas reinhardtii transcription factor PSR1 is required for the control of activities involved in scavenging phosphate from the environment during periods of phosphorus limitation. Increased scavenging activity reflects the development of high-affinity phosphate transport...... hiện toàn bộ
The N-Terminal Domain of the Flo1 Flocculation Protein from Saccharomyces cerevisiae Binds Specifically to Mannose Carbohydrates
American Society for Microbiology - Tập 10 Số 1 - Trang 110-117 - 2011
Katty Goossens, Catherine Stassen, Ingeborg Stals, Dagmara Donohue, Bart Devreese, Henri De Greve, Ronnie Willaert
ABSTRACT Saccharomyces cerevisiae cells possess a remarkable capacity to adhere to other yeast cells, which is called flocculation. Flocculation is defined as the phenomenon wherein yeast cells adhere in clumps and sediment rapidly from the medium in which they ...... hiện toàn bộ
Comparison of Cell Wall Localization among Pir Family Proteins and Functional Dissection of the Region Required for Cell Wall Binding and Bud Scar Recruitment of Pir1p
American Society for Microbiology - Tập 4 Số 11 - Trang 1872-1881 - 2005
Toru Sumita, Takehiko Yoko‐o, Yoh‐ichi Shimma, Yoshifumi Jigami
ABSTRACT We examined the localization of the Pir protein family (Pir1 to Pir4), which is covalently linked to the cell wall in an unknown manner. In contrast to the other Pir proteins, a fusion of Pir1p and monomeric red fluorescent protein distributed in clusters in pir1 Δ cells throughout t...... hiện toàn bộ
