内容説明
The annual Congress of the Italian Biochemical and Molecular Biology Society (SIB) was held in September 1999 in Alghero, Sardegna, Italy. The programme envisaged a symposium on molecular adaptations of haemoglobin function in ver- tebrates. Haemoglobin specialists from several countries were invited to speak at the symposium and paved the way for wide-ranging and stimulating discussions. The symposium contributions have been collected together in this volume. The structure/function relationship in haemoglobins from vertebrates (fishes populat- ing temperate and polar environments, diving birds, marine and terrestrial mam- mals) has been tackled from many angles, focusing on the adaptation of the oxy- gen-transport system to the constraints dictated by the environment. Eleven arti- cles review some of the most recent developments of the studies on this ancient oxygen-transport protein, characterized by high conservation during evolution. The volume offers the reader an updated, state-of-the-art summary of a field that is enjoying a true renaissance.
Covering the topic from several viewpoints, the volume includes protein chemistry (amino acid sequence, secondary, tertiary and quaternary structures, thermodynamics of oxygen-binding features), molecular biology (globin gene structure, sequence, organization, expression and regulation) and evolution. In this representation of effective multidisciplinary and multina- tional collaborative efforts, reference is available to a wide range of disciplines and biological systems. The tools of the investigators comprise advanced and powerful methodologies developed in recent years, e. g.
