FIG 4.

Construction and FAE activities of rR18 and rTH2-18 chimeras. (A) Schematic illustration of the primary structures of rR18, rTH2-18, and the eight chimeras used in this study. The regions marked in black and white represent the sequences of R18 and TH2-18, respectively. aa, amino acids. (B) FAE activities in chimeric FAE lysates. Ethyl ferulate (4 mM) was used as the substrate. Values represent the averages of data from three independent experiments. Error bars represent standard deviations.
