(Logo) Your Protein Structures

IndexAssignments Index

In order to illustrate the concepts of protein structure as the course progresses, all PPS students have been assigned a PDB (Protein Data Bank) file, which corresponds to a particular protein structure determined by X-ray crystallography (although other PDB structures have been determined by other means).

If you are looking at a PDB file for the first time, you will see that the format consists of the co-ordinates of each atom of the molecule, along with a variety of other information at the beginning of the file. Do not be concerned if at this stage you do not understand all of the different types of record in a PDB file.

The main section of the course on Secondary Structure starts next term (at the beginning of May), followed by material on higher structural levels, and you will be using your protein in exercises on protein structure during that part of the course. However, it is also important to understand the molecular composition of the protein you are dealing with and we suggest that between now and the end of the first term (week 11) you examine your protein by working through the following.
