Dear all,
I have some N-acetyl-glucosamine (NAG) in my structure. When I
searched the monomer library in CCP4 6.0.1, I found out that NAG is
actually N-acetyl-glucose, which is much less common, I believe. I
downloaded the high-resolution structure of N-acetyl-glucosamine from
HIC-UP and used sketcher to generate a cif library. I named the
sugar NAG. I read this new cif file into refmac5 (5.3) and used
"make check none" in the refinement. I thought my library would
overwrite the NAG in the monomer library in CCP4, but refmac5 still
use the NAG it found from the monomer library. Is there anyway to
make sure refmac5 will use my library even there is another one in
the monomer library with the same name?
Thanks.
