Product Details
Activity |
Catalyzes the cis-trans-isomeration of X-Pro-peptide bonds. The protein folding that is limited by the isomeration of X-Pro-peptide bonds can be accelerated by cyclophilin A. Also binds to cyclosporins and the cyclophilin A/cyclosporin A (Prod. No. BML-SE163). |

Alternative Name |
Peptidylproline cis-trans-isomerase |
Application Notes |
Catalyzes the cis-trans-isomerization of X-Pro-peptide bonds. Protein folding reactions that are limited by the isomerization of X-Pro-peptide bonds are accelerated by cyclophilin A. Cyclophilin A binds tightly to the immunosuppressive agent Cyclosporin A. This complex binds calcineurin (PP2B) and inhibits its phosphatase activity. |
Endotoxin Content |
Packaged under sterile conditions with a maximum endotoxin content of 0.1 EU/μg determined using the chromogenic Limulus amebocyte lysate (LAL) test. |

Handling & Storage
Use/Stability |
Caution: Loss of protein may occur at high dilutions due to adsorption to container surfaces. Freezing of the enzyme or storage of the enzyme in diluted form could lead to loss of activity. In order to best maintain the endotoxin specification and peptidyl prolyl isomerase activity, it is recommended that aliquots be withdrawn with sterile pipet tips, if possible under a sterile hood. |

Source | Produced in E. coli. Human calcineurin Aα (MW 60kDa) and calcineurin B (MW 15kDa) heterodimer. Both subunits are coexpressed in a construct with yeast myristoyl-CoA:protein N-myristoyltransferase. The resulting highly active calcineurin (protein phosphatase 2B) is N-myristoylated on the CaNB subunit, similar to the native protein. |
