Glycyrrhiza uralensis

-

thermostability of wild type isoforms SUS1 and SUS2 is poor at 50°C. Activity loss occurs rapidly with increasing incubation time, and the half-lives are 50 and 25 min for SUS1 and SUS2, respectively. Mutant enzyme SUS1-DELTA9 shows a half-life increase of 2fold. The residual activity is 50% after 100 min, while the wild type activity remains less than 20% of the original activity. The half-life of the variant SUS2-DELTA9 also increases 2fold

Thermosynechococcus vestitus

-

the enzyme remains stable after 10 min incubation up to 50°C, but activity sharply decays beyond 55°C. Addition of 1 mM ADP, 10 mM UDP, or 200 mM Suc enhances the thermal stability by almost 5°C
