Alpha+Beta Topologies


 

Introduction

This is where we collect together all those folds which include significant alpha and beta secondary structural elements, but for which those elements are `mixed', in the sense that they do NOT exhibit the wound alpha-beta topology. This class of folds is therefore referred to as alpha + beta

You should also browse through the Alpha + Beta Class of the CATH Protein Structure Classification Database at University College, London. This lists 3 different architectures (sandwiches, roll and other) with 7, 6 and 14 topologies respectively.

You should also be aware of alternative classifications, such as the Structural Classification of Proteins database (Alexey G. Murzin, Steven E. Brenner, Tim J.P. Hubbard, and Cyrus Chothia). In all, seventy-nine categories of alpha+beta folds are listed. A number of the entries have links to diagrams by Manuel Peitsch. 

Thus we see that this class includes:-
