Zinc Fingers [PDF ebook] 
Structure, Properties and Applications

Zinc fingers are small protein structural motifs that can coordinate one or more zinc ions to help stabilize their folds. They can be classified into several different structural families and typically function as interaction modules that bind DNA, RNA, proteins or small molecules. In this book, the authors present current research in the study of the structure, properties and applications of zinc fingers.
