Background:

Understanding biological pathways requires analyzing process coupling compatible with input-output relations.
Existing algorithms are primarily designed for metabolic pathways where enzymes are not modified by reactions.

Purpose of the Study:

To adapt and apply existing pathway assembly algorithms to a broader range of molecular networks.
To demonstrate the versatility of a single algorithmic procedure across different biological systems.

Main Methods:

Utilized an existing algorithm for assembling metabolic pathways.
Modified the algorithm's input parameters to include proteins as reactants that can be modified by reactions.
Applied the adapted algorithm to model networks for cytoplasmic signal transduction and gene regulation.

Main Results:

The algorithm successfully assembled molecular networks where reactions modify proteins.
The same procedure was effective for assembling pathways in metabolism, cytoplasmic signal transduction, and gene regulation.
Demonstrated the compatibility of the algorithm with different types of biological processes.

Conclusions:

A single algorithmic approach can be used to assemble diverse biological pathways, including those involving protein modification.
This unified procedure simplifies the analysis and understanding of complex molecular networks.
The findings facilitate the study and modification of various biological pathways.
