A protein in its native three dimensional conformation is cleaved with trypsin. According to the amino acid sequence, there are 9 residues where trypsin could cleave, yet only 3 fragments were produced from the digest. What conclusion can be made about protein structure that would lead to this result? The protein has multiple domains b. The protein is highly compacted, minimally accessible by solvent molecules c. The protein has quaternary structure d. The protein has a dynamic structure, highly accessible by solvent molecules e. The protein is compromised only of alpha helices
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.
