Resumo

The backbone 1 H, 13 C and 15 N chemical shifts of cyclophilin (CyP) when bound to cyclosporin A (CsA) have been assigned from heteronuclear two‐ and three‐dimensional NMR experiments involving selectively 15 N‐ and uniformly 15 N‐ and 15 N, 13 C‐labeled cyclophilin. From an analysis of the 1 H and 15 N chemical shifts of CyP that change upon binding to CsA and from CyP/CsA NOEs, we have determined the regions of cyclophilin involved in binding to CsA.
