Proximity does not contribute to activity enhancement in the glucose oxidase–horseradish peroxidase cascade

open access: yesNature Communications, 2016
The activity enhancement of the glucose oxide and horseradish peroxidase enzymatic cascade on DNA scaffolds has been linked to proximity effects. Here, the authors challenge this view and suggest that the activity improvement is rather due to the pH near

The combined absence of NF-kappa B1 and c-Rel reveals that overlapping roles for these transcription factors in the B cell lineage are restricted to the activation and function of mature cells [PDF]

open access: yes, 2002
Transcription factors NF-KB1 and c-Rel, individually dispensable during embryogenesis, serve similar, yet distinct, roles in the function of mature hemopoietic cells.

Removal of Phenols with Encapsulated Horseradish Peroxidase in Calcium Alginate [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2009
Horseradish peroxidase was encapsulated in calcium alginate for the purpose of phenol removal. Considering enzyme encapsulation efficiency, retention activity and enzyme leakage of the capsules, the best gelation condition was found to be 1 % w/v of ...

Inhibition of Horseradish Peroxidase Activity by Boroxine Derivative, Dipotassium-trioxohydroxytetrafluorotriborate K2[B3O3F4OH]

open access: yesJournal of Chemistry, 2017
Recently research shows that horseradish peroxidase, HRP, when combined with other compounds, is highly reactive toward different human tumour cells and that better understanding of catalytic mechanism and inhibition HPR could lead to a new targeted ...
