Sorry, that was the wrong zenodo link! The correct one is: https://doi.org/10.5281/zenodo.220983 On Friday, 27 March 2020, 23:06:01 GMT, Jonathan Cooper <00000c2488af9525-dmarc-requ...@jiscmail.ac.uk> wrote: If you can model it as a lysine, it will be the beta-ME adduct. There's a good one in 1b4e (see attached) which Eileen Jaffe pointed out to me and I never got round to sorting out. Now there's another one of 'mine' for which the data have not been deposited, but I did put the images on zenodo 4 years ago (https://doi.org/10.5281/zenodo.51560) if anyone fancies a little lock-down project!!

The surface adduct could easily form during this process. On Mar 27, 2020, at 4:38 PM, Cowan, Richard H.

Adding reducing agent to the purification of the protein would potentially reduce this disulphide, possible causing issues the stability and heterogeneity? At least that's my understanding?
