SO I HAVE ANSWERED ALL THE QUESTION FOR THE MOST PART, BUT I HAVE FOUND IT DIFFICULT TO ANSWER THE LAST QUESTION, PLEASE THERE IS NO NEED TO ANSWER THE FIRST 3 QUESTION JUST THE LAST. THANK YOU.

First go back to the PDB database (http://www.rcsb.org/pdb/) and search for your PDB. What resolution is your structure (smaller is better – we’re aiming at something below 2.5 Angstroms)? ANSWERED.

How many protein chains are present? Each chain will be given a unique letter title. For each chain, given its letter title, actual title (under the heading “Molecule”), and length. ? ANSWERED.

How many unique ligands are present? Provide the name for each unique ligand.? ANSWERED.

1- Give a single sentence description of the probable role of each ligand (point out if something is the solvent, or if something is a coenzyme or a metal ion cofactor, etc.).  NEED HELP WITH. EXPLANATION ABOUT THE ROLE AND FUNCTION OF THE LIGAND, IF ITS A SOLVENT, COENZYME OR METAL ION COFCTOR.

TO SOLVE IT YOU GO TO http://www.rcsb.org/pdb/ OR THIS DIRECT LINK TO THE PDB ( https://www.rcsb.org/3d-view/1DV1?preset=ligandInteraction&sele=PO4 ) AND INPUT THE PDB 1DV1 AND IT BRINGS OUT THE INFORMATION ABOUT IT, THEN YOU CAN GO TO THE PART OF SMALL MOLECULES AND IT CLICK 3D INTERACTION TO GET A GOOD VIEW OF THE LIGAND WHICH SHOULD BE (PO4) THEN PLEASE ANSWER THE QUESTION. IF YOU HAVE A QUESTION PLEASE LEAVE A COMMENT.

Explanation / Answer

Give a single sentence description of the probable role of each ligand (point out if something is the solvent, or if something is a coenzyme or a metal ion cofactor, etc.).

single sentence description :

each ligand should be an ion or molecule attached to a metal atom by coordinate bonding.
