^a MFA predicted the maximum growth yield with 1,2,4-TCB as the sole carbon source.
^b Pathways obtained using BNICE and pathway search algorithm, up to length 15.
^c Pathways that: (i) did not involve any novel intermediates and (ii) were shorter than or equal to the length of the known pathway, which involved 10 steps.
^d Pathways that produced physiologically feasible flux profiles (did not involve any blocked reactions).
