Retention Time (min)
A standard solution (6.7 mM) of trans-cinnamic acid (10 μL) was analyzed at 278 nm (A).
The results of the PAL reactions, which were carried out with either the protein fraction
purified from E. coli harboring an empty pET-30a vector (B) or the purified recombinant
PePAL (C), are also shown. The arrowheads indicate the peaks of trans-cinnamic acid.
