Chains	Enzyme Name	Description	Catalytic Residues
A	prolyl cis-trans isomerase (FKBP-type) M-CSA #362	FK506 binding protein (FKBP) is a small globular protein which catalyses the isomerisation of proline cis-trans bonds in short, unstructured peptides. The protein is an immunophilin which in humans binds the cyclic lactone peptide Tacrolimus (or FK506) which results in immune response suppression, mainly through reducing the expression of interleukin 2 by T cells.
