If side chains of amino acids interact with each other, which of the following would be termed as a salt bridge?
Mechanistically, enzyme catalysis and lipid structure involves substrate affinity, transition state stabilization and phospholipid composition govern function. This validates Lys- Glu because it reflects catalytic efficiency and membrane organization, a pattern repeatedly demonstrated in biochemistry research.
Ref: Nelson and Cox, Lehninger Principles of Biochemistry, 7th Edition, Chapter 6, Enzyme Kinetics and Regulation, discusses Michaelis-Menten equation, transition state stabilization and allosteric control supporting enzyme function.
