  • Isolated genes encoding peptidyl prolyl-cis.trans-isomerase and plasmids comprising said genes
    Patent number: 5416015
    Abstract: A yeast PPIase characterized by possessing following properties: (1) acting on and isomerizing the bond X.sub.aa -Pro (wherein X.sub.aa stands for any amino acid and Pro stands for L-proline), (2) exhibiting a single molecular weight of about 17,000 daltons in the sodium dodecyl sulfate-polyacrylamide concentration gradient gel electrophoresis, (3) exhibiting a single isoelectric point of about 6.2 in the isoelectric focusing, and (4) inhibited by CsA;an E. coli PPIase-.beta. characterized by possessing the following properties: (1) acting on and isomerizing the bond X.sub.aa -Pro (wherein X.sub.aa stands for any amino acid and Pro for L-proline), (2) exhibiting a single molecular weight of about 20,000 daltons in the sodium dodecyl sulfate-polyacrylamide concentration gradient gel electrophoresis, (3) exhibiting a single isoelectric point of about 5.0 in the isoelectric focusing, and (4) no being inhibited by CsA;an E. coli PPIase-.alpha.
    Type: Grant
