Fig. 6From: Heterologous expression of nattokinase from B. subtilis natto using Pichia pastoris GS115 and assessment of its thrombolytic activityThe optimal temperature and pH for NK-Bs. A The optimal temperature for NK-Bs. The enzyme activity at 65 °C was set to 100%. The absolute enzyme activity, corresponding to 100% activity, was 465 U/mL. B The optimal pH for NK-Bs. The enzyme activity at pH 9.0 was set to 100%. The absolute enzyme activity, corresponding to 100% activity, was 371.7 U/mLBack to article page
