Volume 1 & 2 of the “Handbook of Metalloproteins”, focuses on a number of metals, including iron, nickel, manganese, cobalt, copper and vanadium. Now volume 3 extends the wealth of knowledge to focus on proteins found in the redox–inactive ions of zinc and calcium. While there are more than two hundred known 3D structures of zinc enzymes, the handbook focuses on contributions for those enzymes most relevant in research today. Also covered extensively, is the role of calcium ions as secondary messengers in controlling the many biological processes. Each metalloprotein included is supported by extensive detail, including; Colour graphical representations of the 3D structure Functional class Occurrence Spectroscopic data Reviews from Volumes 1 & 2 "it is a pleasure just to read this handsome and carefully produced work" (Angewandte Chemie, Vol.41, 2002) “…it is a pleasure to use ...this excellent, authoritative, and valuable text... I regard this work as essential for library purchase..." (Natural Products Report, Vol.19, No.4, 2002) “…highly recommended as a resource for bioinorganic chemistry. It will have lasting value for researchers in the field…” (The Alchemist – Chemweb, 2002)
