    Classification: Transport Protein
    Structure Weight: 20939.30
    Molecule: NITROPHORIN 4
    Polymer: 1 Type: protein Length: 184
    Chains: A
    Details: NITRIC OXIDE OCCUPIES THE SIXTH COORDINATION POSITION OF THE IRON. THE HEME IS DISORDERED BY A ROTATION OF 180 DEGREES AROUND THE CHA-FE-CHC AXIS. THE ONLY EVIDENCE OF THIS DISORDER IS THE APPEARANCE OF METHYL GROUPS CMB AND CMC AS VINYLS. THESE EXTRA ATOMS ARE CALLED CBBB AND CBCB.
