Enzyme Immobilization Technologies and Industrial Applications

open access: yesACS Omega, 2023
Enzymes play vital roles in diverse industrial sectors and are essential components of many industrial products. Immobilized enzymes possess higher resistance to environmental changes and can be recovered/recycled easily when compared to the free forms ...

The carbohydrate-active enzyme database: functions and literature

open access: yesNucleic Acids Res., 2021
Thirty years have elapsed since the emergence of the classification of carbohydrate-active enzymes in sequence-based families that became the CAZy database over 20 years ago, freely available for browsing and download at www.cazy.org. In the era of large

Phoresis and Enhanced Diffusion Compete in Enzyme Chemotaxis [PDF]

open access: yesNano Lett. 2018, 18, 4, 2711-2717, 2021
Chemotaxis of enzymes in response to gradients in the concentration of their substrate has been widely reported in recent experiments, but a basic understanding of the process is still lacking. Here, we develop a microscopic theory for chemotaxis, valid for enzymes and other small molecules.

Characteristics of the microplate method of enzyme-linked immunosorbent assay for the detection of plant viruses.

open access: yesJournal of General Virology, 1977
Some characteristics of a microplate method for the detection and assay of plant viruses using enzyme-labelled antibodies are described. The method enabled the highly sensitive detection of a number of morphologically different viruses in purified ...

Nasal Gene Expression of Angiotensin-Converting Enzyme 2 in Children and Adults.

open access: yesJournal of the American Medical Association (JAMA), 2020
This study compares angiotensin-converting enzyme 2 (ACE2) gene expression, which has been associated with SARS-CoV-2 cell entry, in the nasal epithelium of children vs adults.

Accelerated search kinetics mediated by redox reactions of DNA repair enzymes [PDF]

open access: yesBiophysical 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.

An insertion/deletion polymorphism in the angiotensin I-converting enzyme gene accounting for half the variance of serum enzyme levels.

open access: yesJournal of Clinical Investigation, 1990
A polymorphism consisting of the presence or absence of a 250-bp DNA fragment was detected within the angiotensin I-converting enzyme gene (ACE) using the endothelial ACE cDNA probe. This polymorphism was used as a marker genotype in a study involving 80

A Novel Angiotensin-Converting Enzyme–Related Carboxypeptidase (ACE2) Converts Angiotensin I to Angiotensin 1-9

open access: yesCirculation Research, 2000
ACE2, the first known human homologue of angiotensin-converting enzyme (ACE), was identified from 5′ sequencing of a human heart failure ventricle cDNA library.
