a possibility, if you must try, would be to look at intein-based protein ligation. Hideo Iwai has a series of papers on this over the last 15+ years. Adrian On 26 Jul 2023, at 11:14, Armando Albert mailto:xalb...@iqfr.csic.es>> wrote: Dear all, We are trying to characterize a protein consistin

Hi Armando At the risk of appearing flippant, why not submit the sequence of the full-length protein to something like Alphafold (readily available to all via ColabFold (see https://colab.research.google.com/github/sokrypton/ColabFold/blob/main/AlphaFold2.ipynb)? I suspect that each of the t

Dear all, We are trying to characterize a protein consisting of two domains. We have successfully produced, purified and crystallized both domains independently. However, we are unable to overexposes a soluble form of the full-length protein. Can anyone provide a strategy to merge back the ind
