The Advances in Enzymology and Related Areas of Molecular Biology Series is one of the most prestigious in the field, devoted to the latest trends in molecular biology and enzymology. Each volume of the series contains contributions from leading authorities in the field. Under Dr. Purich's editorship, which began with volume 72, the series has expanded its coverage to include thematic volumes focusing on specific research areas, as well as non-thematic volumes consisting of chapters with a more general appeal.
