- trna model
-
- Data Files:
-
- A F-MET t-RNA modelled by Prabhakaran was used.
-
- A secondary structure assignment was made automatically:
- pdb-nuc-pdb trna.pdb trna.ss
-
- This file was then edited by hand to add a code for the "domains"
- of the tRNA molecule.
-
- The *.ribbons file consists of only one filename:
- ls calmod.ss > calmod.ribbons
-
- This file was then edited to add a special color file, "nucleic.color".
-
- The *.coords file consists of only one filename:
- ls trna.pdb > trna.coords
-
- This file was then edited to add the special "nucleic" key.
-
- The *.model file file was created, then edited to change the menu name:
- pdb-model trna.pdb trna.model
-
- The model was displayed at this stage to color and
- select the special "base-attachment" bonds:
- ribbons
- ( display the ribbon, open Ribbon Panel.
- set Sequence Color = "dom",
- set Print Select = "base-A", Print File => trna_ba0.rcyl
- Exit ribbons )
-
- This cylinder file was renamed:
- mv trna_ba0.rcyl trna_ba.rcyl
-
- The *.bonds file consists of only one filename:
- ls trna_ba.cyl > trna.bonds
-
- Create the solid aromatic ring polygons:
- pdb-nuc-ring trna.pdb trna-ring.tri
-
- Create the *.polys file from this single set:
- ls trna-ring.tri > trna.polys
-
-
- The complete nucleic acid model is now ready for display.
-
-
-
- Image File: rna.rgb
-
- The model was displayed with default settings on the Ribbon Panel
- for everything except:
- Sequence Color = "dom"
- Ribbon Style = "Square"
- Ribbon Texture = "Dipole"
- Sheet Width = "6.0"
- Helix Width = "0.3"
- Ribbon Sample = "13"
- The image was saved from the Geom Panel.
