Consider the trypsin binding-pocket specificity structure
scenario and critical AAs interactions within: G226-D189-G216 (see
slide): a single nucleotide polymorphism within the D189 codon
resulted in a first nucleotide Guanine replacement by Cytosine.
What is the consequence of this mutation relative to binding
pocket- substrate specificity?
