Characterization of recombinant EstPS1. (a) Determination of the optimum substrate for EstPS1. The relative activity (%) was obtained by comparison of the substrates (C4). (b) Optimum temperature of p-nitrophenyl butyrate for EstPS1 activity. (c) Optimum pH of p-nitrophenyl butyrate with EstPS1. (d) pH stability of p-nitrophenyl butyrate with EstPS1 in different buffers for 20 h at 30 °C.
