[ccp4bb] Refmac5: C-terminal amidation parameters

2014-12-08 Thread Markus Schneider
Dear all, refinement of my protein structure involves a C-terminal amide. Looking through the monomer/link library files mon_lib_list.cif and mon_lib_ind.cif I could not identify a modification or link suitable for amide restraints. I know I could construct a proper .cif myself, however I a

This is where it’s customary to include a small image or two (or better, a link thereto) which shows the density, and the masters here can tell you there best guesses—seems to be a bit of a parlour game. Also include info on what is in the crystallization condition and protein buffer if you dare

2014-12-08 Thread Yamei Yu
Hi all, We crystallised a small GTPase expressed in E. Coli and found some densities in GDP/GTP binding site. We didn’t add any GDP/GTP or GDP/GPD homologues during protein expression, purification and crystallisation. The resolution is not high, we couldn’t tell what it is. Is there any method
