Practice question
Question
The N-end rule pathway determines protein degradation based on:
Explanation
The stability of its N-terminal residue is the accurate response regarding enzymatic activity or regulation described in this question. Enzymes are biological catalysts that accelerate reactions by lowering activation energy through specific substrate binding and transition state stabilization. In the context of Protein Degradation, The stability of its N-terminal residue plays a specific catalytic or regulatory role determined by its active site configuration and mechanism of action. The other options (The charge of the protein, The hydrophobicity of the protein, and The number of disulfide bonds) are either different enzymes with distinct substrate specificities, act through different mechanisms, or are involved in separate metabolic pathways.
