Application of hybrid LRR technique to protein crystallization Jin MS; Lee JOBMB Rep 2008[May]; 41 (5): 353-7LRR family proteins play important roles in a variety of physiological processes. To facilitate their production and crystallization, we have invented a novel method termed "Hybrid LRR Technique". Using this technique, the first crystal structures of three TLR family proteins could be determined. In this review, design principles and application of the technique to protein crystallization will be summarized. For crystallization of TLRs, hagfish VLR receptors were chosen as the fusion partners and the TLR and the VLR fragments were fused at the conserved LxxLxLxxN motif to minimize local structural incompatibility. TLR-VLR hybridization did not disturb structures and functions of the target TLR proteins. The Hybrid LRR Technique is a general technique that can be applied to structural studies of other LRR proteins. It may also have broader application in biochemical and medical application of LRR proteins by modifying them without compromising their structural integrity.|Animals[MESH]|Crystallization/methods[MESH]|Humans[MESH]|Leucine-Rich Repeat Proteins[MESH]|Models, Biological[MESH]|Protein Structure, Tertiary[MESH]|Proteins/*chemistry/genetics/*metabolism[MESH]|Recombinant Proteins/chemistry/metabolism[MESH]|Toll-Like Receptors/chemistry/genetics/metabolism[MESH] |
