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 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...
متن کاملProlyl isomerases in yeast.
Prolyl isomerases are enzymes that catalyze cis-trans isomerization of peptidyl-prolyl bonds and span three structurally unrelated protein families: the cyclophilins, FKBPs, and parvulins. The genome of the budding yeast Saccharomyces cerevisiae encodes eight different cyclophilins (Cpr1 to Cpr8), four FKBPs (Fpr1 to Fpr4), and a single parvulin (Ess1). Remarkably, two of these proteins, cyclop...
متن کاملMycobacterium tuberculosis Peptidyl-Prolyl Isomerases Also Exhibit Chaperone like Activity In-Vitro and In-Vivo
Peptidyl-prolyl cis-trans isomerases (Ppiases), also known as cyclophilins, are ubiquitously expressed enzymes that assist in protein folding by isomerization of peptide bonds preceding prolyl residues. Mycobacterium tuberculosis (M.tb) is known to possess two Ppiases, PpiA and PpiB. However, our understanding about the biological significance of mycobacterial Ppiases with respect to their plei...
