FIG. 3.
(A) Temperature dependence of the activity of recombinant MPGS (•) and the recombinant MPGP (○). The enzyme activities were determined at between 25 and 103°C. The inset shows the Arrhenius plot of the data at between 40 and 90°C. (B) pH dependence of the recombinant MPGS (solid symbols) and the recombinant MPGP (open symbols) of T. thermophilus HB27. The enzyme activities were determined at between pH 4.5 and 9.0 in MES (▵), Tris-HCl (▪ and □) and Bis-Tris propane (• and ○).
