Full text Abstract
Figure 2.
Fig. 2. Molscript (51) overlay of the stuctures of C. elegans cyclophilin 3 and human cyclophilin A. The eight labeled strands are shown in purple, the two helices are shown in green, and ceCYP3 loop structure is shown in orange. The human CypA loop (in blue) contrasts with the shape adopted by the divergent loop, which is formed mainly by 7 additional residues (48KSGKPLH54) in the CYP-3 sequence.
Figure 3.
Fig. 3. Stereo diagram showing the active sites of CYP-3 and human cyclophilin A. This clearly shows the complete conservation of all 13 residues important in the binding of CsA, with the only significant structural difference between human CypA and CYP-3 being in the conformation adopted by Arg62 that places the side chain atoms 0.7Å apart.
