I picked the protein named: Bovine eNOS N368D single mutant with L-N(omega)-Nitroarginine-(4R)-Amino-L-Proline Amide Bound from the protein data bank web site : Bank. There are many hetero compounds in that are embedded within this protein such as ACETATE ION (ACT), L-N(OMEGA)-NITROARGININE-(4R)-AMINO-L-PROLINE AMIDE ( DP9), GLYCEROL(GOL), 5,6,7,8-TETRAHYDROBIOPTERIN(H4B), PROTOPORPHYRIN IX CONTAINING FE(HEM), and ZINC ION(ZN). I chose the hetero compound which has the HET code is DP9 to work on this project.

I extracted the hetero compound from the protein, and I sketched its structure in ChemSketch.  After that I converted it to 3D in Chemsketch to have more detailed picture about this hetero compound.  I also have a copy of hetero compound in DSV program in order to fix its structure incase its extracted structure is not the same as its original that embed within the protein(1ZZS).
