英文摘要Cyclophilins (cyps) are a widespreading protein family in living organisms and possess the activity of peptidyl-prolyl cis-trans isomerase (ppiase), which is inhibited by cyclosporin a (csa). the human nuclear cyclophilin (hcyp33) is the first protein which was found to contain two rna binding domains at the amino-terminus and a ppiase domain at the carboxyl-terminus. we isolated the hcyp33 gene from the human hematopoietic stem/progenitor cells and expressed it in escherichia coli, and determined the crystal structure of the c domain of hcyp33 at 1.88 angstrom resolution. the core structure is a beta-barrel covered by two alpha-helices. superposition of the structure of the c domain of hcyp33 with the structure of cypa suggests that the c domain contains ppiase active site which binds to csa. furthermore, c domain seems to be able to bind with the gag-encoded capsid (ca) of hiv-1 and may affect the viral replication of hiv-1. a key residue of the active site is changed from ala-103-cypa to ser-239-hcyp33, which may affect the ppiase domain/substrates interactions.
