SRP selectively recognizes ER signal sequences on newly synthesized proteins. This is an outcome of
Mechanistically, enzyme catalysis and lipid structure involves substrate affinity, transition state stabilization and phospholipid composition govern function. This validates Formation of covalent intermediate because it reflects catalytic efficiency and membrane organization, a pattern repeatedly demonstrated in biochemistry research.
Ref: Lehninger Principles of Biochemistry, Chapter 9, Lipids and Membranes, explains phospholipid components, glycerol, fatty acids, phosphate group and membrane structure providing foundation for lipid biochemistry.
