I'm trying to incorporate a DAB (2,4-Diaminobutyric Acid) residue into my peptide sequence. I found the CCP code 'Dab' in the Molecules/Add Sequence window, and appended that to the sequence. It seemed to work, in terms of generating a valid peptide sequence, however the resonances for Dab that it comes up with in the Molecule:Atom Browser window aren't what I was expecting (it has Hda and Hdb resonances, instead of Hz*).
So, I'm wondering if the CCP code 'Dab' is not 2,4-Diaminobutyric Acid. Is there a list somewhere of the chemical structures that match the CCP codes given in the drop-down menu (Molecules:Add Sequence window)? I can't seem to find a list on the web anywhere.
Or alternatively, is this an error in how the Dab residue was put in?
Any help gratefully received.
