abstract = {Corynebacterium glutamicum belongs to the microbes of
enormous biotechnological relevance. In particular, its
strain ATCC 13032 is a widely used producer of L-amino acids
at an industrial scale. Its apparent robustness also turns
it into a favorable platform host for a wide range of
further compounds, mainly because of emerging bio-based
economies. A deep understanding of the biochemical processes
in C. glutamicum is essential for a sustainable enhancement
of the microbe's productivity. Computational systems biology
has the potential to provide a valuable basis for driving
metabolic engineering and biotechnological advances, such as
increased yields of healthy producer strains based on
genome-scale metabolic models (GEMs). Advanced
reconstruction pipelines are now available that facilitate
the reconstruction of GEMs and support their manual
curation. This article presents iCGB21FR, an updated and
unified GEM of C. glutamicum ATCC 13032 with high quality
regarding comprehensiveness and data standards, built with
the latest modeling techniques and advanced reconstruction
pipelines. It comprises 1042 metabolites, 1539 reactions,
and 805 genes with detailed annotations and database
cross-references. The model validation took place using
different media and resulted in realistic growth rate
predictions under aerobic and anaerobic conditions. The new
GEM produces all canonical amino acids, and its phenotypic
predictions are consistent with laboratory data. The in
silico model proved fruitful in adding knowledge to the
metabolism of C. glutamicum: iCGB21FR still produces
L-glutamate with the knock-out of the enzyme pyruvate
carboxylase, despite the common belief to be relevant for
the amino acid's production. We conclude that integrating
high standards into the reconstruction of GEMs facilitates
replicating validated knowledge, closing knowledge gaps, and
making it a useful basis for metabolic engineering.},
