| Method |
Abstract:"The unknown ATP stoichiometry parameters of the constructed E. coli network were estimated from experimental data of eight different aerobic chemostat experiments carried out with E. coli MG1655, grown at different dilution rates (0.025, 0.05, 0.1, and 0.3 h(-1)) and on different carbon substrates (glucose, glycerol, and acetate)." |
| Comments |
"The estimated ATP stoichiometry parameters are shown
in Table VIII. It can be seen from this table that the
estimated d is significantly lower than the maximum
theoretical value (2.0). Although under high oxygen levels
(as was the case in [investigators’] chemostat cultures) the predominant
terminal oxidase is of the bo-type with an H?+/e- ratio of 2,
under these conditions also the NDH2 dehydrogenase,
which does not contribute to the pmf, is known to be
expressed (see Theoretical Aspects Section). This implies
that the expected d under these conditions would be between
1.0 and 2.0, which corresponds well with the estimated value
of 1.49." "It is also worthwhile to compare [investigators’] in vivo E. coli results
with those for S. cerevisiae (Van Gulik and Heijnen, 1995)
and P. chrysogenum (Van Gulik et al., 2001) which are of the
same order of magnitude (Table VIII). [Investigators’] estimation of the
d of E. coli lies between the values for S. cerevisiae and
P. chrysogenum. The growth related maintenance coefficient
for E. coli was similar as for P. chrysogenum whereas the
growth independent maintenance coefficient was two times
higher for E. coli." |
