Table 3. Comparison of flux ranges, reaction essentialities and metabolite producibilites in ECC2 and ECGS for growth on glucose.

Property Proportions
Flux ranges (under growth-optimality; Fi is the difference of maximal and minimal flux of reaction i)
 Inline graphic 290/499 (58.1%)
 Inline graphic 153/499 (30.7%)
 Inline graphic| 29/499 (5.8%)
 Inline graphic 27/499 (5.4%)
Essentialities of reactions
Essential for growth (ECC2/ECGS) 411/290
 ● for protected reactions (ECC2/ECGS) 7/6
Not essential for growth but growth-rate limiting (ECC2/ECGS) 17/16
 ● for protected reactions (ECC2/ECGS) 8/7
No effect, growth rate >95% of μmax (ECC2/ECGS) 71/193
 ● for protected reactions (ECC2/ECGS) 50/52
Producibilities of metabolites
 Maximal product yield in ECC2 >95% of maximal product yield in ECGS 378/486 (77.8%)
 Maximal product yield in ECC2 >80% and <95% of maximal product yield in ECGS 55/486 (11.3%)
 Maximal product yield in ECC2 <80% of maximal product yield in ECGS 53/486 (10.9%)

Comparisons were restricted to those reactions and internal metabolites that are present in ECC2.
