== 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.

X-ray structures and analysis of 11 cyclosporin derivatives complexed with cyclophilin A.,Kallen J, Mikol V, Taylor P, Walkinshaw MD J Mol Biol. 1998 Oct 23;283(2):435-49. PMID:9769216<ref>PMID:9769216</ref>
