- Data Files:
-
- The tetrameric human oxy-hemoglobin was taken from the
- Protein Data Bank (code is "1HHO").
- The "1hho.pdb" file was edited to remove all but the main reference.
- The "1hho_*.pdb" files have undergone manipulation for a local
- research project. The crystallographically
- related dimer was generated, and renumbering done to conform
- to the peculiarities of XPLOR.
-
- The *.coords file consists of only four filenames:
- ls 1hho_A.pdb > globin.coords
- ls 1hho_B.pdb >> globin.coords
- ls 1hho_C.pdb >> globin.coords
- ls 1hho_D.pdb >> globin.coords
-
- A secondary structure assignment was made based on H-bonding:
- pdb-pro-pdb 1hho_A.pdb 1hho_A.ss
- pdb-pro-pdb 1hho_B.pdb 1hho_B.ss
-
- The *.ribbons file consists of only four filenames (note the
- use of the same SS file, as the molecules are two-fold related):
- ls 1hho_A.pdb > globin.coords
- ls 1hho_B.pdb >> globin.coords
- ls 1hho_A.pdb >> globin.coords
- ls 1hho_B.pdb >> globin.coords
-
- This file was then edited to add a special color file, "protein.color".
-
- Separate files were generated for each of the four porphyrin rings
- and for each of the four iron atoms. This was done with the
- shell script "1hho_H.csh":
- csh 1hho_H.csh
-
- The *.model file was generated, and edited to give a different
- name and to reflect the tru center of the tetramer:
- pdb-model 1hho_.pdb globin.model
-
- The mulitmeric protein ribbon model is now ready for display.
