Hi,

I am a PhD student at the University of Warwick (UK).

I am contacting you to know if I can modify a pdb structure in ChimeraX. I would need to create a covalent bond between the epsilon -NH2 group of a Lys residue and the hydroxyl group of fructose to make a  bond like R-CH2-NH-R'. Is this modification possible in Chimera X? If so, how can I do this?

Best wishes,

Lucia
