Question

Lysozyme is an enzyme that breaks down bacterial cell walls and is found in your tears, mucus, and saliva. A mutation occurs in the gene for lysozyme that results in a lysine (a positively charged amino acid) being substituted for an arginine (also a positively charged amino acid). Do you think that the mutant lysozyme will function similarly to the normal lysozyme?


A.) yes,because protein function stays the same no matter what mutations occur.
B.) no, because all changes in protein primary sequence result in functional differences
C.) no, because changing lysine to arginine will cause the protein to denature.
D.) yes, because both lysine and arginine are positievly charged to the teriary structure and therefore function should be similar.



Please help , Thank yoU!!!
