Hi Engin, The latest version of the Refmac dictionary has the correct geometry (and loads of other improvements). You can download it here: http://www.ysbl.york.ac.uk/~garib/refmac/latest_refmac.html Cheers, Robbie Joosten > Hi everyone, > > We just realized in the lab that the dimethyl-lysine in the ccp4 monomer > database (MLY) has planar tertiary amines, instead of trigonal pyramid > with ~109º degree angles (which we have fixed for our purposes).
