Leucine Rich Repeats: Second Edition

This book explores the structure, function, and evolution of Leucine Rich Repeat (LRR) proteins by characterizing eight major families of LRR units through their amino acid sequences and tertiary structures. Tandem LRRs assemble into distinctive helical architectures with diverse structural parameters, enabling a wide range of biological functions across eukaryotes, prokaryotes, and viruses.The work examines the relationship between LRR structural diversity and functional specialization, providing insights into how these repeat proteins contribute to biological processes. It also investigates the evolutionary pathways of LRR proteins, revealing how variations in sequence and three-dimensional organization have shaped their adaptation and diversification. By integrating molecular structure, bioinformatics, and evolutionary analysis, this book offers a comprehensive perspective on one of the most versatile protein repeat systems in biology.
