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.
-
运输条件
In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.

Protein Description
EntB is a non-ribosomal peptide synthetase (NRPS) that plays a crucial role in the biosynthesis of the siderophore enterobactin, which is produced by various pathogenic bacteria, including Escherichia coli. Siderophores are high-affinity iron-chelating compounds that enable bacteria to sequester iron from their environment, which is vital for their growth and virulence, particularly in iron-depleted conditions such as those found in host organisms. The study of EntB is significant because understanding its structure and function can provide insights into the mechanisms of iron uptake in pathogenic bacteria, potentially leading to new antimicrobial strategies. Additionally, the reconstitution of EntB as a recombinant protein allows for detailed biochemical and structural characterization, facilitating the elucidation of its enzymatic activity and interactions with other components of the enterobactin biosynthetic pathway. Elucidating the functional properties of recombinant EntB can also aid in the development of inhibitors that target this pathway, providing a novel approach to combating infections caused by enteric pathogens. Given the increasing resistance to conventional antibiotics, research on EntB and its associated biosynthetic mechanisms is vital for identifying new targets for drug development, highlighting the broader implications of this work in the field of microbial pathogenesis and therapeutic innovation.
