Through tissues, phosphorylated sugars are carried via certain
protanes. While trying to figure out the specific amino acids
that are related to this interaction the most, you mutated lysin in
active-site. You found the main aminoacids from affinity change
that happened in mutant protein in a comparison to the nonmutanted
protein.
I). Is this a fibrous or globular protein?
II). In order to make sure it travels through bloodstream, the
exterior has hydrophobic or hydrophilic aminoacids?
III). Given answers you’ve chosen, if you wanted to stop lysine
binding in activesite, which one would you pick for
substitution? aminoacids; - K, D, R or H?
Why would this answer you have chosen, be able to stop
binding (Relative to sidechain chamistry)?
Provide brief and concise explanation.
