Model cupredoxines (azurin and others) employed to study of structural functional relationships within protein electron‑transport systems
2022
Abstract
Biochemical processes like photosynthesis and cellular respiration, which involve redox reactions and are facilitated by electron transfer through a cascade of protein molecules, commonly referred to as electron-transfer systems, play a key role in all life on Earth. Azurin is a suitable model to study structural properties of such electron-transfer systems and the role of individual amino acid residues or the central metal ion in redox reactions.
This protein belongs to the family of small soluble electron transporters known as cupredoxines and has a physiological role during anaerobic respiration in Pseudomonas bacterial species.
