Peptidyl-Prolyl cis-trans Isomerase (PPIase) assays
Having worked wit Selcia on a number of projects I always keep an eye out for news on their work on Peptidyl-Prolyl cis-trans Isomerases (PPIase). These are very interesting class of enzymes whose principal function is to catalyse the cis-trans isomerisation of the X-Pro peptide bonds in polypeptide chains (where X is any amino acid). This transformation is thought to be a mechanism to modulate protein function.
PPIase enzyme targets are of increasing interest in drug discovery due to the extensive potential of small molecule inhibitors in a range of therapeutic areas, including infection, inflammation, cancer and neuroprotection.
Selcia have now expanded the range of Peptidyl-Prolyl cis-trans Isomerase (PPIase) assays they can offer.
