Revision as of 01:23, 11 March 2011

Introduction

• Overview of the talk
  • My Recent Research
  • Cursory coverage of several free (and mainly open-source) options for molecular visualization

• Mutagenesis using PyMOL. Similar approach can be done in Swiss-PDB Viewer (a.k.a. DeepView).

Yeast snoRNAs

• Introduction to snoRNAs - most modify and are not-essential to yeast
• Nobel prizes 2009 studies of the structure and function of the ribosome structure
  • Jmol
    • The Application
    • The Java Applet - Demonstration
  • Locations of the modifications in the context of the functional ribosome
  • Yeast snoRNA database
  • Turns out of you remove clusters of modifications or modifications at critical locations and examine processing of pre-rRNA and properties of mature ribosome, find effects.

Jmol

• Advanced Options
  • Console
  • Works with small molecules too
    • Works with small molecules too and even can do energy minimization with them
    • Can be used to show chemical reactions
  • Compare Command Demonstration
• 3D options - Demo with 3D ribosomal modifications maps database - Paint Your Own

Protein Data Bank

• over 70,000 X-ray crystallography, NMR, and cryo-EM structures
• about 85% are crystallographic structures
• Metaphor with electron density
• Caveat: Keep in mind these are models - Not all models or even portions of models created equally

Proteopedia

• Proteopedia - interactive 3D encylopedia of macromolecular structures and structural biology resources to which scientists contribute and use to share structural biology content
• People behind Proteopedia
  • Proteopedia:Team
  • Users, like You!

Types of Proteopedia pages

• Topic Pages
  • Macromolecular Structures
  • About Macromolecular Structure
• PDB Entry Pages
• User space Pages
• Sandbox Pages
• Workbench Pages
• Interactive 3D Complements (I3DC) - Journal of Biological Inorganic Chemistry
• Administrative
  • How To/Guides
  • Organizational/Table of Contents
  • Main Page - the main gateway

Topic Pages

• Examples of structure pages
  • the ribosome structure; contrast with entry at PDB
  • Hemolysin
    • Quality toggle
    • Popup
  • Citrate Synthase
  • The Glutamate Receptor (GluA2)
    • Proteopedia pages can be exported for offline viewing using the toolbox on the left.
• Information and Resource Collection, as well
  • About Macromolecular Structure
  • Cation-pi interactions
  • Searching

User Pages

• Other users cannot edit pages in this space

PDB Entry Pages

• Proteopedia has an entry for every PDB entry (over 70,000) with interactive scene links and links to useful resources
  • Example 1m10
  • Random Example: 1p3v (PDB 4 digit alphanumeric accession number)
    • Conservation: , explanation, and see also The ConSurf Database and The ConSurf Server Other examples: 4enl or 5cyt

FirstGlance in Jmol

• Views and Convenience buttons
  • How many chains? - Use 3pla
  • Key Resources:
    • Biological Unit
    • Missing pieces?; PDBsum link on Proteopedia entry pages helpful for this as well

Structural Biology for Non-structural Biologists

• MolviZ "Top 5" by Eric Martz
• Polyview-3D = fancy PyMol views and animations made super easy via a web server with forms.
  • Example - 3pla
  • Makes animations too and/or morphs too with multiple model structures

Proteopedia Page Authoring

• Model of a wiki
• Sandbox - there is a "student" login that can be used by groups for editing these for teaching purposes
• Conveniences
  • Buttons for 3D structure windows and other commonly used items
  • Since a large amount of references are from Pub-Med, PMID all that is needed for references

Proteopedia Scene Authoring

• Scene Authoring Tools
  • Load a structure 2zi0 or previous scene
  • Set your scene. Undo/Redo features.
  • Save your scene
  • Add the scene to the page
• Try it out and then add and improve. Repeat.

Acknowledgements

• closing slides

Time permitting

• Pymol to Jmol conversion built into Proteopedia's Scene Authoring Tools
• Students at UMASS in classes associated with Chemistry-Biology Interface program design presentations for showing on the Molecular Playground
• Morphing allows displaying the visual transition between two molecular conformations.
• Jmol works with small molecules too
  • • Works with small molecules too and even can do energy minimization with them
    • Can be used to show chemical reactions

Resources

Macromolecular Visualization

• Eric Martz's recent workshop at his list of workshops.

• About Macromolecular Structure
• FirstGlance in Jmol is very useful for exploring PDB entries or upload structure files.
• Jmol Protein Explorer's powerful Quickviews approach really helps quickly generate useful views. This effort is building Chime-based Protein Explorer to work with Jmol, and a few features may still not yet work.
• MolviZ "Top 5"
• MolviZ.Org
• Protein Explorer's Glossary
• Jmol Application
• PyMol
• Polyview-3D, fancy PyMol views and animations made super easy via a web server with forms.
