Practical Template-Based Modelling
includes homology modelling, fold recognition and visualisation

This site is a complementary guide for the theroretical part of the course. You'll find examples and useful resources regarding protein structure prediction. This is a GUIDE, it is not intended to be a tutorial or similar resource. The practical parts have been divided in several blocks.

1.-First choose one of the target sequences in the list and run BLAST against the PDB database from one of the two links below

2.-Second, Consult the " Blast decision table" below to decide which approach is the proper one for the following targets



PDB blast decision table

:::: [BACK TO TOP]
Can you find a PDB structure with an e-value of less than 0.01?

Does the target have > 25% ID with any PDB structure?

Is the aligned length more than 80% of total length of the target sequence?

Are there few gaps in the alignment?

If the answer is YES to all If you answered NO to any question
Then Consider Homology modelling (opens in a new window) More work is needed. Go to Template-based Modelling (opens in a new window)
