The phrase "activity over a broad" is not correct and seems incomplete in written English.
It may be intended to describe a range of activities or a broad scope of engagement, but it lacks clarity and context.
Example: "The research focused on activity over a broad spectrum of environmental factors."
Alternatives: "activity across a wide range" or "activity over a wide area".
The enzyme retained more than 50% of its maximal activity over a broad range of pH values (4.5 7.5).
It exhibits absolute activity over a broad pH range of 5.0 –9.0 and found to be resistant to hydrolytic enzymes: trypsin, proteinase K and lipase.
It was found that γ-MnO2 showed considerable activity over a broad range of pH and temperature as well as desired reusability for four consecutive cycles.
Understanding the mechanisms that dictate protein stability is of large relevance, for instance, to enable design of temperature-tolerant enzymes with high enzymatic activity over a broad temperature interval.
Based on the NiCo2O4 MS showed excellent peroxidase-like activity over a broad temperature range, especially at normal body temperature, a detection tool was designed for glucose determination in diabetics' serum samples.
Additionally, AMPs exhibit antibacterial activity over a broad range of pH and temperatures.
Lip6, lip13ss and pl1 exhibited >50%% activity in the pH range of 6.5 8.0, while lip4 showed activity over a broader pH range as it presented 53 % of its maximum activity level at pH 10. Pl2ss had optimum pH at 8.5, respectively, and presented activity >50%% in alkaline pH range 8.5 10.0 (Fig. 2).
Hence, B. stratosphericus lipase has preferred the high temperature of 50 °C for maximal activity although the lipase was active over a broad range of temperature between 30 and 80 °C.
Optimum temperature was found to be 50°C, supporting activity (60%100%%) over a broad temperature range (30 60°C).
As in our previous work [ 14], we carried out activity measurements over a broad range of E2 concentrations.
The activity of the recombinant Xyn2 was highest at 60°C and it was active over a broad range of pH (3.0 8.0) with maximal activity at pH 6.0.
