Dear all,
I’m trying to solve a structure of a (modified) hexapeptide:
- inhouse (very decent) data up to 0.8 Angstrom
- average redundancy = 10
- according to the Matthews coefficient of 1.88 with 34.77 %solvent, there should be 3 Nmol/asym
- ‘large’ unit cell of about a=54, b=54, c=12
- SG = P3(1)12 or P3(2)12
As there’s (presumably) only C, H, N and O in the structure, I’m not able to solve this via Direct Methods, Charge Flipping etc,.
Trying MR (with Phaser) doesn’t give any results either, as there’s hardly any homologous models
Has anyone encountered a similar problem please, and could provide any possible solutions?
(building in heavy atoms isn’t my first option at the moment,. )
Thank you very much
Regards
Kristof
