Protein Structure and Function. Primers in Biology. Edition No. 1

  • ID: 5224716
  • Book
  • August 2003
  • 180 Pages
  • John Wiley and Sons Ltd
Protein Structure and Function considers the key concepts of protein structure and function and the relationship between sequence, structure and function with clear, concise explanations and full colour illustrations.

- Written by two outstanding names in the field, Gregory Petsko and Dagmar Ringe. - Considers the principles of protein structure and folding, functional properties of proteins and regulation of protein function, and introduces the basic principles whereby structure and function are deduced from sequence. - Fully up-to-date with emphasis on what sequence can tell you about structure and function. - Ideal for undergraduates and graduates studying the fundamental principles of protein structure and function in departments of biochemistry and molecular biology, and working scientists needing an up-to-date introduction to the field.
