OpenFLUX: efficient modelling software for 13C-based metabolic flux analysis [PDF]

open access: yesMicrobial Cell Factories, 2009
Abstract Background The quantitative analysis of metabolic fluxes, i.e., in vivo activities of intracellular enzymes and pathways, provides key information on biological systems in systems biology and metabolic engineering. It is based on a comprehensive approach combining (i) tracer cultivation on 13C substrates, (ii)

Glycerol metabolism of Pichia pastoris (Komagataella spp.) characterised by 13C-based metabolic flux analysis

open access: yesNew Biotechnology, 2019
Metabolic flux analysis based on 13C-derived constraints has proved to be a powerful method for quantitative physiological characterisation of one of the most extensively used microbial cell factory platforms, Pichia pastoris (syn. Komagataella spp.). Nonetheless, the reduced number of carbon atoms and the symmetry of the glycerol molecule has hampered

13C-based metabolic flux analysis

open access: yesNature Protocols, 2009
Stable isotope, and in particular (13)C-based flux analysis, is the exclusive approach to experimentally quantify the integrated responses of metabolic networks. Here we describe a protocol that is based on growing microbes on (13)C-labeled glucose and subsequent gas chromatography mass spectrometric detection of (13)C-patterns in protein-bound amino ...

Metabolic fluxes in recombinant Streptomyces lividans analyzed with 13 C-based metabolic flux analysis

open access: yesIFAC-PapersOnLine, 2016
Abstract: Streptomyces lividans is an interesting host for the production of heterologous proteins. Expression of these foreign proteins often results in a metabolic burden leading to unsatisfactory yields. In this work, metabolic fluxes in Streptomyces lividans producing thermostable cellulase A are quantified.

Validation-based model selection for 13C metabolic flux analysis with uncertain measurement errors.

open access: yesPLoS Computational Biology, 2022
Accurate measurements of metabolic fluxes in living cells are central to metabolism research and metabolic engineering. The gold standard method is model-based metabolic flux analysis (MFA), where fluxes are estimated indirectly from mass isotopomer data

Analysis of metabolic flux in felid spermatozoa using metabolomics and 13C-based fluxomics†

open access: yesBiology of Reproduction, 2019
Spermatozoa from three feline species-the domestic cat (Felis catus), the cheetah (Acinonyx jubatus), and the clouded leopard (Neofelis nebulosa)-were analyzed using metabolomic profiling and 13C-based fluxomics to address questions raised regarding their energy metabolism.

GC/MS-based 13C metabolic flux analysis resolves the parallel and cyclic photomixotrophic metabolism of Synechocystis sp. PCC 6803 and selected deletion mutants including the Entner-Doudoroff and phosphoketolase pathways

open access: yesMicrobial Cell Factories, 2022
Background Cyanobacteria receive huge interest as green catalysts. While exploiting energy from sunlight, they co-utilize sugar and CO2. This photomixotrophic mode enables fast growth and high cell densities, opening perspectives for sustainable ...

Validation of carbon isotopologue distribution measurements by GC-MS and application to 13C-metabolic flux analysis of the tricarboxylic acid cycle in Brassica napus leaves

open access: yesFrontiers in Plant Science, 2023
The estimation of metabolic fluxes in photosynthetic organisms represents an important challenge that has gained interest over the last decade with the development of 13C-Metabolic Flux Analysis at isotopically non-stationary steady-state.

Integration of a constraint-based metabolic model of Brassica napus developing seeds with 13C-Metabolic Flux Analysis

open access: yesFrontiers in Plant Science, 2014
The use of large-scale or genome-scale metabolic reconstructions for modeling and simulation of plant metabolism and integration of those models with large-scale omics and experimental flux data is becoming increasingly important in plant metabolic ...
