2. Using a new ligand description

Description:
Refinement of a new structure from the PDB that contains a ligand missing in the CCP4 dictionary

Project directory:         jligand/2_newligand/
Reflection data:            4do4.mtz
Structure:                     4do4.pdb

3. Using a new ligand and link descriptions

Description:
Additional dictionary is generated defining two entries:
– covalent link between PLP and LYS and
– isolated ligand formed by covalently bound PLP and Methyl-ASP
A structure containing two forms of bound PLP is completed and refined.

Project directory:         jligand/3_newlink/
Reflection data:            1ajs.mtz
Incomplete structure:   model.pdb
