Immunophilins and parvulins. Superfamily of peptidyl prolyl isomerases in Arabidopsis.
Immunophilins are defined as receptors for immunosuppressive drugs including cyclosporin A, FK506, and rapamycin. The cyclosporin A receptors are referred to as cyclophilins (CYPs) and FK506- and rapamycin-binding proteins are abbreviated as FKBPs. These two groups of proteins (collectively called immunophilins) share little sequence homology, but both have peptidyl prolyl cis/trans isomerase (...
متن کاملInsights into the catalytic mechanism of peptidyl prolyl cis/trans isomerases.
A large body of physiological, cell biological, kinetic and structural data about peptidyl prolyl cis/trans isomerases (PPIases) has been accumulated during the past 20 years, but despite the simplicity of the catalyzed reaction the question of how the enzyme action is performed is still not fully answered. In this review the center of attention is the molecular background of the catalytic mech...
متن کاملPeptidyl-prolyl isomerases: a new twist to transcription.
Peptidyl-prolyl isomerases (PPIs) catalyse the cis-trans isomerisation of peptide bonds N-terminal to proline residues in polypeptide chains. They have roles in the folding of newly synthesised proteins and in the function of the immune system. In addition, members of the parvulin-like family of PPIs have been implicated in cell cycle control. Their activity is directed by the prior phosphoryla...
متن کاملStructural and Biochemical Characterization of the Human Cyclophilin Family of Peptidyl-Prolyl Isomerases
Peptidyl-prolyl isomerases catalyze the conversion between cis and trans isomers of proline. The cyclophilin family of peptidyl-prolyl isomerases is well known for being the target of the immunosuppressive drug cyclosporin, used to combat organ transplant rejection. There is great interest in both the substrate specificity of these enzymes and the design of isoform-selective ligands for them. H...
