稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
保存条件 & 期限
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Protein Description
NirK is a copper-containing nitrite reductase that plays a crucial role in the denitrification process, converting nitrite (NO2-) to nitric oxide (NO), which is an essential step in the nitrogen cycle. The enzyme is primarily found in various bacteria, including pathogenic strains, where it facilitates anaerobic respiration and contributes to nitrogen removal from the environment. The study of NirK recombinant proteins has gained significant attention due to its potential applications in biotechnology and environmental science. Understanding the structural and functional characteristics of NirK can provide insights into enzyme mechanism, substrate specificity, and its role in microbial ecology. Furthermore, the recombinant expression of NirK allows researchers to produce sufficient quantities of the protein for detailed biochemical assays and structural studies. Recent advancements in protein engineering and purification techniques have enabled the exploration of NirK variants and their catalytic efficiencies. As environmental concerns grow regarding nitrogen pollution, characterizing NirK and similar enzymes could lead to innovative strategies for bioremediation and sustainable agriculture, highlighting their relevance in addressing global environmental challenges. Thus, the research on NirK recombinant proteins not only enhances our understanding of microbial metabolism but also underscores their potential in developing eco-friendly solutions to mitigate nitrogen-related issues.
