de.NBI Systems Biology Service Center (de.NBI-SysBio)

The aim of the project is bioprospecting, isolation and characterization of novel secondary metabolites, produced by extremophilic microorganisms. The project is dedicated to a poorly investigated problem of antagonistic interactions between extremophilic microorganisms in their communities, namely, to the investigation of the ability of extremophiles to produce secondary metabolites with biocidic, cytotoxic and cytostatic activities. Working out this problem will fulfill an important applied

Public showcase and collection of training material

The workshop focuses on the publication, curation, retrieval, and usage of kinetic data from the reaction kinetics database SABIO-RK and on the use of data in modeling. There will be experience reports from scientists who successfully used experimental data to formulate or verify biological hypotheses with the computer, and you will experience how experimental data can be used with computational models.

ZucAt - Sucrose (from german Zucker) translocation in Arabidopsis thaliana. Sucrose translocation between plant tissues is crucial for growth, development and reproduction of plants. Systemic analysis of this metabolic process and underlying regulatory processes can help to achieve better understanding of carbon distribution within the plant and the formation of phenotypic traits. Sucrose translocation from ‘source’ tissues (e.g. mesophyll) to ‘sink’ tissues (e.g. root) is tightly bound to the

Sucrose translocation between plant tissues is crucial for growth, development and reproduction of plants. Systemic analysis of this metabolic process and underlying regulatory processes can help to achieve better understanding of carbon distribution within the plant and the formation of phenotypic traits. Sucrose translocation from ‘source’ tissues (e.g. mesophyll) to ‘sink’ tissues (e.g. root) is tightly bound to the proton gradient across the membranes. The plant sucrose transporters are grouped

we describe a multi-compartmental model consisting of a mesophyll cell with plastid and mitochondrion, a phloem cell, as well as a root cell with mitochondrion. In this model, the phloem was considered as a non-growing transport compartment, the mesophyll compartment was considered as both autotrophic (growing on CO2 under light) and heterotrophic (growing on starch in darkness), and the root was always considered as heterotrophic tissue completely dependent on sucrose supply from the mesophyll

The multi-compartmental metabolic network of Arabidopsis thaliana was reconstructed and optimized in order to explain growth stoichiometry of the plant both in light and in dark conditions. Balances and turnover of energy (ATP/ADP) and redox (NAD(P)H/NAD(P)) metabolites as well as proton in different compartments were estimated. The model showed that in light conditions, the plastid ATP balance depended on the relationship between fluxes through photorespiration and photosynthesis including both

The solution of Flux Balance Analysis (FBA) represents metabolic flux distribution in ZucAt model under light growth conditions. In this solution, (i) the ratio photorespiration / photosynthesis has been fixed to 0.25; and (ii) cyclic electron flow through FQR (ferredoxin-plastoquinone reductase) has been set 0.1 from non-cyclic flow through FRN (ferredoxin-NADP oxidoreductase). Under this constraints, ATP formed by non-cyclic photophosphorylation is not sufficient to fulfill ATP/NADPH ratio for

The solution of Flux Balance Analysis (FBA) represents metabolic flux distribution in the model under light growth conditions. In this solution, (i) the photorespiration was set to 0; and (ii) cyclic electron flow through FQR (ferredoxin-plastoquinone reductase) has been set of 0.1 of flow through FRN (ferredoxin-NADP oxidoreductase). Under this constraints, ATP is under-produced in plastid and therefore is additionally imported to cytoplasm. Flux through FQR represents cyclic electron flow through

The solution of Flux Balance Analysis (FBA) represents metabolic flux distribution in ZucAt model under light growth conditions. In this solution, (i) the ratio photorespiration / photosynthesis has been fixed to 0.25; and (ii) cyclic electron flow through FQR (ferredoxin-plastoquinone reductase) has been set 0.5 from non-cyclic flow through FRN (ferredoxin-NADP oxidoreductase). Under this constraints, ATP is over-produced in plastid and a surplus is exported to cytoplasm. Flux through FQR

The solution of Flux Balance Analysis (FBA) represents metabolic flux distribution in ZucAt model under light growth conditions. In this solution, (i) the ratio photorespiration / photosynthesis has been fixed to 0.25; (ii) and ATP transport between plastid and cytoplasm has been set to 0. The last constraint allows finding the ratio between fluxes through FQR (ferredoxin-plastoquinone reductase) and FRN (ferredoxin-NADP oxidoreductase) under which the ATP balance in plastid becomes self-sufficient

This is BIOMD0000000005.

The model presents a multi-compartmental (mesophyll, phloem and root) metabolic model of growing Arabidopsis thaliana. The flux balance analysis (FBA) of the model quantifies: sugar metabolism, central carbon and nitrogen metabolism, energy and redox metabolism, proton turnover, sucrose translocation from mesophyll to root and biomass growth under both dark- and light-growth conditions with corresponding growth either on starch (in darkness) or on CO2 (under light). The FBA predicts that
