How does Z-LLG-βNA work within enzymatic assays, and what makes it a preferred
substrate in such setups?
Z-LLG-βNA functions as an enzymatic substrate designed to investigate
the activity of proteolytic enzymes within biochemical assays. The mechanism by which Z-LLG-βNA operates
is based on its structure and the subsequent interaction with target enzymes. Typically, Z-LLG-βNA
comprises a peptide sequence (Z-LLG) linked to a 4-nitroanilide group (βNA). This design allows the
substrate to mimic natural peptides that proteases would typically cleave. When a protease targets this
substrate, it specifically recognizes the peptide bonds within Z-LLG-βNA and catalyzes their hydrolysis.
As a result, the 4-nitroanilide moiety is liberated, which in this case leads to the release of a
fluorescent signal or a colorimetric change depending on the detection system being used.
The
