Concept explainers
a.
To determine:
Whether the aspartate amino acid side chain (a) serve a catalytic function, (b) serve to hold the substrate, or (c) both.
Introduction:
The interaction between the substrate and active site of an enzyme results in the formation of an enzyme-substrate complex. This enzyme-substrate complex is formed due to the different types of attractive force present in between the molecules found in active site of an enzyme and substrate. The types of attractive force which are involved in enzyme-substrate complex are: ionic bonding, covalent bonding, and hydrogen bonding.
b.
To determine:
Whether the phenylalanine amino acid side chain (a) serve a catalytic function, (b) serve to hold the substrate, or (c) both.
