By: Answerout


Here is the answer for the question - Why don't cells rely more on disulfide bridges to stabilize the folding of proteins?. You'll find the correct answer below

Why don't cells rely more on disulfide bridges to stabilize the folding of proteins? Though strong, disulfide bridges put a strain on the backbone. Disulfide bridges can only occur just after proline in the amino acid sequence. There's no room for more disulfide bridges. Most proteins have many of them. They make the protein rigid. Many proteins change their shape as they work. Disulfide bridges are too weak. Proteins can get more stability from ionic forces.

The Correct Answer is

They make the protein rigid. Many proteins change their shape as they work. There may be additional reasons for the low number of disulfide bridges, but one reason is the need for changes in shape. Disulfide bridges make the folding rigid.

Reason Explained

They make the protein rigid. Many proteins change their shape as they work. There may be additional reasons for the low number of disulfide bridges, but one reason is the need for changes in shape. Disulfide bridges make the folding rigid. is correct for Why don't cells rely more on disulfide bridges to stabilize the folding of proteins?
