Product Introduction
N-Benzoyl-L-tyrosine ethyl ester (BTEE) is a widely used chromogenic substrate for the detection of serine protease activity, particularly chymotrypsin. It is an esterified derivative of L-tyrosine, designed to mimic natural peptide substrates recognized by proteolytic enzymes.
Upon enzymatic hydrolysis, BTEE undergoes cleavage of the ester bond, resulting in a measurable change in absorbance, allowing quantitative monitoring of enzyme activity.
Due to its specificity and reliability, BTEE is commonly used in enzyme kinetics studies, protease activity assays, inhibitor screening, and biochemical research, especially in systems involving chymotrypsin-like enzymes.
Mechanism of Reaction
N-Benzoyl-L-tyrosine ethyl ester functions as a substrate for serine proteases.In enzymatic reactions:
- It is hydrolyzed by chymotrypsin and related proteases
- The ester bond is cleaved
- Produces N-benzoyl-L-tyrosine and ethanol
This makes BTEE a classical substrate for studying protease catalysis and enzyme specificity.
