Up, Down, and Around: Identifying Recurrent Interactions Within and Between Super-secondary Structures in β-Propellers

Research output: Contribution to book/anthology/report/proceedingBook chapterResearch

The examination and analysis of super-secondary structures or other specific structural patterns associated with particular functions, sequence motifs, or structural contexts require that the set of structures examined shares the same feature. This seems obvious but in practice this may often present problems such as identifying complete sets of data avoiding false positives. In the case of the β-propeller structures the symmetry of the propeller creates problems for many structure similarity search programs. Here we present a procedure that will identify propeller structures in PDB and assign them to the different N-propeller types. In addition we outline methods to examine similarities and differences within and between the four stranded up-and-down blades of the β-propeller.
