abstract = {Enterococcus faecalis is a versatile lactic acid bacterium
with a large variety of implications for humans. While some
strains of this species are pathobionts being resistant
against most of the common antibiotics, other strains are
regarded as biological protectants or even probiotics.
Accordingly, E. faecalis strains largely differ in the size
and content of their accessory genome. In this study, we
describe the genome-scale metabolic network reconstruction
of E. faecalis ATCC 19433, a non-resistant human-associated
strain. A comparison of the genome-scale metabolic model
(GSM) of E. faecalis ATCC 19433 with a previously published
GSM of the multi-resistant pathobiontic E. faecalis V583
reveals high similarities in the central metabolic abilities
of these two human associated strains. This is reflected,
e.g., in the identical amino acid auxotrophies. The ATCC
19433 strain, however, has a 14.1 $\%$ smaller genome than
V583 and lacks the multiple antibiotic resistance genes and
genes involved in capsule formation. Based on the measured
metabolic fluxes at different growth rates, the energy
demand at zero growth was calculated to be about 40 $\%$
lower for the ATCC 19433 strain compared to V583.
Furthermore, the ATCC 19433 strain seems less prone to the
depletion of amino acids utilizable for energy metabolism.
This might hint at a lower overall energy demand of the ATCC
19433 strain as compared to V583.},
