Fig. 4From: Characterization of cold-active trehalose synthase from Pseudarthrobacter sp. for trehalose bioproductionEffects of temperature on the activity and stability of PaTreS with maltose as substrate. Enzyme activities at various temperatures (4–70 °C) were assayed. To examine the thermal stability, the enzymes were incubated at various temperatures (4–70 °C) for 6 h and then were immediately cooled. The residual activities were measured at 40 °CBack to article page
