Abstract
The formation of inclusion bodies in bacterial hosts poses a major challenge for the large-scale recovery of bioactive proteins. The process of obtaining bioactive protein from inclusion bodies is labor intensive, and the yields of recombinant protein are often low. Here, we describe a novel method for the renaturation and purification of inclusion bodies. This method combines a scFv-oligopeptide chaperoning system and an on-column refolding system to help refold human muscle creatine kinase (HCK) inclusion bodies. This method could significantly increase the activity recovery of denatured HCK inclusion bodies and provides an effective method for the production of bioactive proteins from inclusion bodies.

Abstract
Protein-folding can go wrong in vivo and in vitro, with significant consequences for the living organism and the pharmaceutical industry, respectively. Here we propose a design principle for small-peptide-based protein-specific folding modifiers. The principle is based on constructing a "xenonucleus", which is a prefolded peptide that mimics the folding nucleus of a protein. Using stopped-flow kinetics, NMR spectroscopy, Förster resonance energy transfer, single-molecule force measurements, and molecular dynamics simulations, we demonstrate that a xenonucleus can make the refolding of ubiquitin faster by 33 ± 5%, while variants of the same peptide have little or no effect. Our approach provides a novel method for constructing specific, genetically encodable folding catalysts for suitable proteins that have a well-defined contiguous folding nucleus.
