Abstract:
:Owing to their structural flexibility, most serpins inhibit the cognate proteases in a fast and specific manner and also are susceptible to pathogenic misfolding. In this issue of Cell Chemical Biology, Madsen et al. (2016) report on the selection and characterization of an RNA aptamer that stabilizes α1-antichymotrypsin L55P mutant without interfering with the protease inhibitory activity.
