htrinsically disordered or unstructured sequences within a protein O allow keratins to form coiled-coils O allow for selective passage of proteins across the nuclear pore complex O All of these are correct. can be observed using X-ray crystallography because they tend to form crystal structures.
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.
Introduction
Proteins are formed by 20 standard amino acids with the limited amino acids availability they get arranged in various orders to form new proteins. So, the sequence of amino acids in the protein varies greatly.
Protein can form generally 4 types of structures:
- Primary structure
- Secondary structure
- Tertiary structure
- Quaternary structure
