1cyn Summary



The structure was published by Mikol, V., Kallen, J., and Walkinshaw, M.D., in 1994 in a paper entitled "X-Ray Structure of a Cyclophilin B/Cyclosporin Complex: Comparison with Cyclophilin a and Delineation of its Calcineurin-Binding Domain." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.85 Å and deposited in 1995.

The experimental data on which the structure is based was not deposited.
