Abstract

The TPR motif is an evolutionary conserved motif involved in diverse cellular processes, thought to mediate protein-protein interactions. A model system for studying TPR-mediated interactions is provided by the yeast CDC23 and CDC27 proteins, components of the anaphase promoting complex (APC). The solution structure of a TPR motif of CDC27, essential for interaction with CDC23 will be solved. Deletion mapping will define the minimal region of CDC23 required for the interaction. Further NMR experiments will provide the first detailed insight into a TPR-mediated interaction. We shall then exploit the structural information and the sequence degeneracy displayed by TPR motifs to explore the feasibility of using a forced molecular evolution approach to design a new TPR motif with new, defined, substrate binding properties.
