Reporter genes offer several advantages in catalysis research: 1. Quantitative Measurement: They allow for the precise quantification of gene expression, providing data on how different factors influence catalytic activity. 2. Real-Time Monitoring: The activity of reporter genes can be monitored in real-time, enabling researchers to observe dynamic changes in enzymatic processes. 3. High Sensitivity: Reporter genes can detect even small changes in gene expression, making them ideal for studying subtle effects in catalytic reactions.
