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.

Identification of functionally related enzymes by learning-to-rank methods [PDF]
arXiv, 2014 Enzyme sequences and structures are routinely used in the biological sciences as queries to search for functionally related enzymes in online databases. To this end, one usually departs from some notion of similarity, comparing two enzymes by looking for correspondences in their sequences, structures or surfaces. For a given query, the search operation

Absolute diffusion measurements of active enzyme solutions by NMR [PDF]
, 2018 The diffusion of enzymes is of fundamental importance for many biochemical processes. Enhanced or directed enzyme diffusion can alter the accessibility of substrates and the organization of enzymes within cells. Several studies based on fluorescence correlation spectroscopy (FCS) report enhanced diffusion of enzymes upon interaction with their ...

Enzyme localization can drastically affect signal amplification in signal transduction pathways [PDF]
, 2007 Push-pull networks are ubiquitous in signal transduction pathways in both prokaryotic and eukaryotic cells. They allow cells to strongly amplify signals via the mechanism of zero-order ultrasensitivity. In a push-pull network, two antagonistic enzymes control the activity of a protein by covalent modification.

Regulating Retinoic Acid Availability during Development and Regeneration: The Role of the CYP26 Enzymes. [PDF]
, 2020 This review focuses on the role of the Cytochrome p450 subfamily 26 (CYP26) retinoic acid (RA) degrading enzymes during development and regeneration. Cyp26 enzymes, along with retinoic acid synthesising enzymes, are absolutely required for RA homeostasis
