(i) Describe the structure of SOD1. (ii) Describe the active site of this enzyme clearly indicating the metal ions involved, their coordination numbers, the geometry around the metal ions and the names of the amino acids directly coordinated to these metal ions. (iii) What is the role of each metal ion? (iv) Draw and explain the catalytic cycle for the conversion of the superoxide anion.
Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
![There are three different types of SOD enzymes in the human body named
SODI, SOD2 and SOD3. The most important is SOD1.
