Table 1 Ranking criteria in the order they are applied to the pathway candidates

From: Network design and analysis for multi-enzyme biocatalysis

Position

Criterion

Comment

1

Number of active reactions

Shorter pathways are

  

favourable

2

Candidate starts with basic metabolites only

’yes’ is preferred

3

Number of reactions without Δ r G

As few as possible

4

\(\sum (\Delta _{r}G + |\Delta _{r}G|)\)

Preferably all Δ r G are

  

negative

5

\(\sum \Delta _{r}G\)

Negative is preferred

6

Number of heterologous enzymes

As few as possible

7

Number of cofactors

As few as possible
