A rigorous method for identifying biochemical reaction or metabolic pathway
s through its systematic synthesis has been established. The current method
for synthesizing networks of metabolic pathways follows the general framew
ork of a highly exacting combinatorial method. The method is capable of gen
erating not only all combinatorially independent, feasible reaction network
s only once, but also those combinations of independent pathways. A case st
udy involving the conversion of glucose to pyruvate with 14 elementary reac
tions illustrates the efficiency and efficacy of the method. All the result
s have been obtained with a PC (Pentium-III 550 MHz, 256 MB RAM) within 1 s
