'''HUMAN CYCLOPHILIN A COMPLEXED WITH 1-(6,7-DIHYDRO)MEBMT 2-VAL 3-D-(2-S-METHYL)SARCOSINE CYCLOSPORIN'''<br />


==Overview==
==HUMAN CYCLOPHILIN A COMPLEXED WITH 1-(6,7-DIHYDRO)MEBMT 2-VAL 3-D-(2-S-METHYL)SARCOSINE CYCLOSPORIN==
Eight new X-ray structures of different cyclophilin, A/cyclosporin-derivative complexes are presented. These structures, combined with the existing three published cyclosporin complexes, provide, a useful structural database for the analysis of protein-ligand, interactions. The effect of small chemical differences on protein-ligand, hydrogen-bonding, van der Waals interactions and water structure is, presented.

== Publication Abstract from PubMed ==
Eight new X-ray structures of different cyclophilin A/cyclosporin-derivative complexes are presented. These structures, combined with the existing three published cyclosporin complexes, provide a useful structural database for the analysis of protein-ligand interactions. The effect of small chemical differences on protein-ligand hydrogen-bonding, van der Waals interactions and water structure is presented.
