TranscriptomicsTranscription profiling of yeast to investigate the involvement of Snf7 and Rim101 in regulation of TIR1 and anaerobically up-regulated genes
Despite the scientific and applied interest in anaerobic metabolism of Saccharomyces cerevisiae, not all genes whose transcription is up-regulated under anaerobic conditions have yet been linked to known transcription factors. Experiments with a reporter construct in which the promoter of the anaero...

TranscriptomicsTranscription profiling of S. cerevisiae to investigate formaldehyde as source of free-energy during growth on glucose
Previously, it has been demonstrated that formate can be utilized by Saccharomyces cerevisiae as additional energy source using cells grown in a glucose-limited chemostat. Here, we investigated utilization of formaldehyde as co-substrate. Since endogenous formaldehyde dehydrogenase activities were i...

TranscriptomicsTemperature-dependent transcriptional response under anaerobic C and N limitations in Yeast
The global transcriptional response of Saccharomyces cerevisiae was investigated in low temperature chemostat cultures grown in carbon or nitrogen limitation. During steady state chemostats, the growth rates and in vivo fluxes were kept constant however the growth-limiting nutrient was significantly...

TranscriptomicsEngineering topology and kinetics of sucrose metabolism in Saccharomyces cerevisiae for improved ethanol yield
Sucrose is a major carbon source for industrial bioethanol production by Saccharomyces cerevisiae. In yeasts, two modes of sucrose metabolism occur: (i) extracellular hydrolysis by invertase, followed by uptake and metabolism of glucose and fructose, and (ii) uptake via sucrose-H+ symport followed b...

TranscriptomicsTranscriptional responses of yeast to preferred and non-preferred nitrogen sources in C-lim chemostat cultures
Aerobic, glucose-limited chemostat cultures of Saccharomyces cerevisiae grown with six different nitrogen sources were subjected to transcriptome analysis. The use of chemostats enabled an analysis of nitrogen-source-dependent transcriptional regulation at a fixed specific growth rate. A selection o...

TranscriptomicsTranscription profiling of S. cerervisiae chemostat growth samples reveals resistance to hop iso-I?-acids in yeast involves active export and vacuolar sequestration
The hop plant, Humulus lupulus L., contains an exceptionally high content of secondary metabolites, the hop iso-α-acids, which possess a range of beneficial properties including antiseptic action. Studies performed on the mode of action of hop iso-α-acids have hitherto been restricted to lactic ac...

TranscriptomicsA Saccharomyces cerevisiae strain with a minimal complement of glycolytic genes reveals strong redundancies in central metabolism
As a result of ancestral whole genome and small-scale duplication events, the genome of Saccharomyces cerevisiaeM-bM-^@M-^Ys, and of many eukaryotes, still contain a substantial fraction of duplicated genes. In all investigated organisms, metabolic pathways, and more particularly glycolysis, are spe...

TranscriptomicsResolving phenylalanine metabolism sheds light on natural synthesis of benzylpenicillin in Penicillium chrysogenum
Industrial production of penicillin G by Penicillium chrysogenum requires medium supplementation with the side chain precursor phenylacetate. However, P.chrysogenum grown in presence of phenylalanine as sole nitrogen source formed detectable extracellular amounts of phenylacetate and penicillin G. T...

TranscriptomicsImpact of Velvet complex on transcriptome and penicillin G production in glucose-limited chemostat cultures of a beta-lactam high-producing Penicillium chrysogenum strain
The multi-component global regulator Velvet complex has been identified as a key regulator of secondary metabolite production in Aspergillus and Penicillium species. Previous work indicated a massive impact of PcvelA and PclaeA deletions, two key components of the Velvet complex, on penicillin produ...

TranscriptomicsAn alternative, arginase-independent pathway for arginine metabolism in Kluyveromyces lactis involves guanidinobutyrase as a key enzyme
Most available knowledge on fungal arginine metabolism is derived from studies on Saccharomyces cerevisiae, in which arginine catabolism is initiated by releasing urea via the arginase reaction. Orthologs of the S. cerevisiae genes encoding the first three enzymes in the arginase pathway were cloned...
