Accelerated search kinetics mediated by redox reactions of DNA repair enzymes [PDF]
Biophysical Journal, volume 96, pp 3949-3958, (2009), 2009 A Charge Transport (CT) mechanism has been proposed in several papers (e.g., Yavin, et al. PNAS, v102 3546 (2005)) to explain the localization of Base Excision Repair (BER) enzymes to lesions on DNA. The CT mechanism relies on redox reactions of iron-sulfur cofactors that modify the enzyme's binding affinity.

Immobilization of Enzymes in Protein Films [PDF]
, 2020 Heterogeneous biocatalysis usually involves the use of immobilized enzymes on solid supports. Enzymes have suitable properties in terms of efficiency and selectivity for use as immobilized catalysts. Different approaches have been developed for effective immobilization, including adsorption, covalent binding, entrapment, encapsulation, and cross ...

Identification of novel small molecule inhibitors of ETS transcription factors
FEBS Letters, EarlyView.ETS transcription factors play an essential role in tumourigenesis and are indispensable for sprouting angiogenesis, a hallmark of cancer, which fuels tumour expansion and dissemination. Thus, targeting ETS transcription factor function could represent an effective, multifaceted strategy to block tumour growth. The evolutionarily conserved E‐Twenty‐Six

miRNA‐29 regulates epidermal and mesenchymal functions in skin repair
FEBS Letters, EarlyView.miRNA‐29 inhibits cell‐to‐cell and cell‐to‐matrix adhesion by silencing mRNA targets. Adhesion is controlled by complex interactions between many types of molecules coded by mRNAs. This is crucial for keeping together the layers of the skin and for regenerating the skin after wounding.

Substrates modulate charge-reorganization allosteric effects in protein-protein association [PDF]
arXiv, 2021 Protein function may be modulated by an event occurring far away from the functional site, a phenomenon termed allostery. While classically allostery involves conformational changes, we recently observed that charge redistribution within an antibody can also lead to an allosteric effect, modulating the kinetics of binding to target antigen.
