Hi Afshan,
in Coot select calculate --> other modeling tools --> find ligands
In 0.6.2, there is a message that ligands are limited to 400 atoms or less.
Regards,
Mitch

Dear Juergen
Many thank for your response yes you have excatly understand my question we have a MR solution of the rest of our protein and just asking how to make my life easier to not built de novo 45-50 residues. so i could not find the option in coot find ligand so, from where i get it?
Best Regards
AFSHAN

why don't you read in that chain in Coot and run the find ligand option with flexible ligand turned on and select that 6kDa ligand ? You should also choose Fo-Fc map to fit the ligand to maybe at 2.7 sigma. You might have to split up the ligand into pieces, not sure what the limitations in Coot/Find Ligand are.
You already have a MR solution of the rest of your protein right ? So you are just asking how to make your life easier to not built de novo 45-50 residues ?

Why not do the molecular replacement - 6kDa is rather small but it most
likely will work

Hello CCP4 user
I have collected a data set 2.1 for my complex. Actually after first
run of Rafmac i can see the density for my inhibitor but the problem
is my inhibitor is 6 KDa and i know the sequence of my inhibitor as
well this inhibitor already crystallize with other protein molecule
present in PDB data bank so how can i put in to that electron density
i mean are there any ways to combine two Pdb in one molecule?
I would be thankful for your help
Best Regards
