Presentation Transcript

Slide 1

NCBI Cn3D4.1 MMDB Structure Tools Introduction to Bioinformatics NSF – UC Davis

Slide 2

NCBI Cn3D4.1 MMDB NCBI Cn3D4.1 VAST Structure seeing Structure arrangements Comparing proteins

Slide 3

MMDB Access amino corrosive and nucleic corrosive successions, and protein structures .pdb, .val, .mage Retrieve PubMed reports Get scientific categorization data View grouping neighbors View structure neighbors

Slide 5

Retrieve a PDB Structure Go to the MMDB page at: http://www.ncbi.nlm.nih.gov/Structure/In the upper right inquiry field enter a PDB/MMDB-Id: (1VID for instance) If you don't have the foggiest idea about a PDB increase ID, look NCBI structure utilizing the quality and additionally protein name (e.g. COMT)

Slide 7

Links to Explore Click the blue protein tab to see the PDB section in GenPept. Examine the record substance Click the blue CDs section to see the Pfam passage in the Conserved Domain Database Click the affix to see VAST structure neighbors (and import them into VAST) Click the methyltransf_3 tab to see "inquiry" succession arrangement against CDD neighbors Follow PDB connection to http://www.rcsb.org/pdb/

Slide 9

Viewing 3D Structures Now pick the dim box – View 3D structure – and select best model, then: Mage RasMol Cn3D You'll need each of these applications. appropriately introduced on your neighborhood PC

Slide 10

3D Structure Viewers Download and introduce MAGE http://kinemage.biochem.duke.edu/kinemage/kinemage.php Download and introduce RasMol http://www.rasmol.org Download and introduce NCBI Cn3D4.1 http://www.ncbi.nlm.nih.gov/Structure/CN3D/cn3d.shtml

Slide 11

NCBI Cn3D Viewer Roughly 2.5 Mbyte download from NCBI Easy to introduce and extremely stable Launches from MMDB (if chose) The Cn3D instructional exercise is lumbering, and the guidelines for VAST arrangement specifically http://www.ncbi.nlm.nih.gov/Structure/CN3D/cn3dtut.shtml

Slide 15

MAGE Viewer Lightweight, simple to introduce Can see little atoms well Good in natural science classes Libraries aren't anything but difficult to discover however Think about utilizing Chime for particles MMDB will send out MAGE records Resolution isn't great by examination

Slide 17

RasMol Structure Viewer Views .pdb documents Very lightweight and capable Has a document to download Coloring chains/bonds is simple Easy to trade into picture documents

Slide 20

PDB - Protein Data Bank http://www.rcsb.org/pdb/Database of more than 35,000 structures Look up a structure by ID, or inquiry Download crude .pdb groups, or .jpeg pictures of structures to incorporate into reports "Particle of the Month" and connections to SCOP and CATH are key website highlights

Slide 22

Cn3D Tutorial You can dispatch Cn3D straightforwardly from the Windows or Mac OS, or from a .val record With Cn3D open, picked document, open, and after that find a document with a .val expansion Or, from MMDB section, pick see 3D structure, best model, with Cn3D show The document will download to your PC Select open from the exchange window

Slide 24

Manipulation of the Image From the picture window, investigate the menu headings (and take as much time as necessary!) File View Show/shroud Style Window Help

Slide 25

Manipulating the Structure You can see the structure in various organizations. Attempt activity, and turn! Approve – now go to view, liveliness, stop! Utilize demonstrate cover up, and pick structures, deposits, adjusted buildups, all that You'll have to go to the Sequence/Alignment Viewer, and select deposits

Slide 26

Sequence Alignment Viewer Take some an opportunity to peruse the menus, as these will turn out to be imperative later View Edit (turned gray until import) Mouse mode Unaligned legitimization (turned gray until import) Imports Now go to imports, indicate imports

Slide 27

Importing Structures This area gets intense. Open instructional exercise! On the off chance that you are working with a topic, have those structures and groupings prepared. Go to Import Viewer, then pick alter, import structures, or import arrangements Hint – import the bigger succession from the littler grouping on the off chance that you have more than one indistinguishable chains (dimers and so on.)

Slide 29

Viewing Aligned Sequences Cn3D4.1 will do a programmed arrangement of arrangements - not expressed in the instructional exercise! Pick combine arrangements, consolidate all You now have a blended grouping Go back to succession/arrangement viewer Aligned deposits are in UPPERCASE! Presently go to Show/Hide adjusted deposits

Slide 34

Problem Posing Compare proteins from various sources, however same moderated space (utilize CDD) HIV/SIV and HTLV/STLV (1ENV protein) Hemoglobin/Myoglobin (2HHD/1M6C) Sequence arrangement is a decent way to deal with phylogenetics works out, esp. change Use NCBI genome to find proteins for HIV, SIV, HTLV, STLV, Prion, SARS, and so forth

Slide 36

Summary Protein structure perception apparatuses can be amusing to utilize, however require bunches of practice Start with NCBI Structure and MMDB Locate the .pdb and .val structure records Open them in RasMol, MAGE, and Cn3D Try doing succession arrangements in Cn3D, utilizing an organic issue (like HIV and so forth.)
