Sorry, that was the wrong zenodo link! The correct one is:

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!!

My guess would be that the chains were prepared under reducing conditions,
mixed, and then allowed to oxidize. The surface adduct could easily form during
this process.

Hi,
The Fab constructs have a c-terminal cysteines on both the heavy and light
chains, which should form a disulphide. 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?
Thanks,

although [BME] seems unlikely, since the crystallized protein is a Fab.
I don't follow.
