The main objectives of SysMO-DB are to: facilitate the web-based exchange of data between research groups within- and inter- consortia, and to provide an integrated platform for the dissemination of the results of the SysMO projects to the scientific community. We aim to devise a progressive and scalable solution to the data management needs of the SysMO initiative, that:

• maximises the ‘shelf life’ and utility of data generated by SysMO;
• provides an integrated platform for the dissemination ...

Cell growth underlies many key cellular and developmental processes, yet a limited number of studies have been carried out on cell-growth regulation. Comprehensive studies at the transcriptional, proteomic and metabolic levels under defined controlled conditions are currently lacking.

This investigation shows public data taken from the BioInvestigation Index. (http://www.ebi.ac.uk/bioinvindex/study.seam?studyId=BII-S-1) Organism: Saccharomyces Cerevisiae

Glycerol, a major by-product of ethanol fermentation by Saccharomyces cerevisiae, is of significant importance to the wine, beer, and ethanol production industries. This investigation aims to gain a clearer understanding of and to quantify the extent to which parameters of the pathway affect glycerol flux in S. cerevisiae.

This investigation represents the data and models submitted to JWS online by Cronwright et al (http://jjj.biochem.sun.ac.za/cgi-bin/getMoreInfo.py?modeldir=cronwright) and ...

Comprehensive high-throughput analyses at the levels of mRNAs, proteins, and metabolites, and studies on gene expression patterns are required for systems biology studies of cell growth [4,26-29]. Although such comprehensive data sets are lacking, many studies have pointed to a central role for the target-of-rapamycin (TOR) signal transduction pathway in growth control. TOR is a serine/threonine kinase that has been conserved from yeasts to mammals; it integrates signals from nutrients or growth ...

Detailed glycolytic model in Lactococcus lactis

A kinetic model of the glycerol synthesis pathway has been constructed. Kinetic parameters were collected from published values. Maximal enzyme activities and intracellular effector concentrations were determined experimentally.

MCA of Glycerol Synthesis in Saccharomyces cerevisiae

Detailed kinetic model for glycolysis of L. lactis. The model is basically the same model as that published by Hoefnagel et al 2002 (Mol. Biol. Reports 29, 157-161). The change made to the model is to make external glucose a variable such that a glucose pulse can be simulated.

An aerobic chemostat culture (above 70% of oxygen saturation) was set up at the specified dilution rate (fraction culture volume per hour; equal to growth rate in steady-state) with a working volume of 1 litre in a 1.5 litre fermenter (Applikon, The Netherlands) using the specified synthetic defined nutrient-limited medium according to the description of Baganz et al., (1997)

Biomass samples (20ml) were taken via the sample port of the Applikon fermenters. The cells were pelleted by centrifugation for 5min at 5000rpm. The supernatant was removed and the RNA pellet resuspended in the residual medium to form a slurry. This was added in a dropwise manner directly into a 5ml Teflon flask (B. Braun Biotech, Germany) containing liquid nitrogen and a 7mm-diameter tungsten carbide ball.
