Protein ‘A’ from Pseudomonas putida contains 135 amino acids. The number of nucleotides present in the gene encoding the
enzyme catalysis and lipid structure analysis shows substrate affinity, transition state stabilization and phospholipid composition govern function. Consequently 408 emerges as the valid choice since it reflects catalytic efficiency and membrane organization, aligning with established principles in biochemistry literature.
Ref: Berg et al., Biochemistry, 9th Edition, Chapter 13, Metabolism and Bioenergetics, covers glycolysis, citric acid cycle, oxidative phosphorylation and NADH-linked reactions detailing biochemical principles.
