Superfamily Cyclophilin-like
Functional Family Peptidyl-prolyl cis-trans isomerase E

Enzyme Information

5.2.1.8
Peptidylprolyl isomerase.
based on mapping to UniProt Q9UNP9
Peptidylproline (omega=180) = peptidylproline (omega=0).
-!- The first type of this enzyme found proved to be the protein cyclophilin, which binds the immunosuppressant cyclosporin A. -!- Other distinct families of the enzyme exist, one being FK-506 binding proteins (FKBP) and another that includes parvulin from Escherichia coli. -!- The three families are structurally unrelated and can be distinguished by being inhibited by cyclosporin A, FK-506 and 5-hydroxy-1,4-naphthoquinone, respectively.
