[Detailed docking of "phospholipid" biological metabolizing pathway].

Objective: To construct protein functional network according to the physiological process in vivo and functionally based distinct families, to understand biological functions, and to make wise decisions.

Methods: We described here a very effective strategy combining with multiple-docking and protein-ligand binding-affinity fingerprint method to generate bio-functional network and pathway and reveal the protein "unknown" functions and their relationship.

Results: Totally 27 sets of proteins and 28 bio-active molecules were used to reconstruct the possible phospholipids metabolic network by computational simulation strategy. The protein-ligand network reconstruction and pathway based drug design showed that the direct interaction investigation might be effective in complex biological system study.

Conclusion: Even for weak and moderate interactions in the real biology system, the relationship between each other can be achieved by fingerprint analysis based on multiple-docking data. The results of these calculations give valuable insight into the pathway and the function relationship among these proteins. This method can be a very useful tool for protein classification, target selection, and inhibitor design.
