Functional Analyses of House Fly Carboxylesterases Involved in Insecticide Resistance

open access: yesFrontiers in Physiology, 2020
Carboxylesterase-mediated metabolism is one of major mechanisms involved in insecticide resistance. Our previous study has identified multiple carboxylesterase genes with their expression levels were significantly upregulated in pyrethroid resistant ...

Opossum carboxylesterases: sequences, phylogeny and evidence for CES gene duplication events predating the marsupial-eutherian common ancestor [PDF]

open access: yes, 2008
Background Carboxylesterases (CES) perform diverse metabolic roles in mammalian organisms in the detoxification of a broad range of drugs and xenobiotics and may also serve in specific roles in lipid, cholesterol, pheromone and lung surfactant ...

Quantitative Analysis Reveals Hitchhiking Drives Polysorbate Hydrolase Persistence Via Host Cell Protein–Antibody Interactions

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Polysorbate‐degrading host cell proteins (HCPs) represent a critical challenge in the manufacturing of monoclonal antibody therapeutics due to their potential to persist during downstream processing. While their enzymatic activity has been characterized, the role of direct HCP‐mAb interactions, particularly those involving polysorbate ...

The effect of the insecticide dichlorvos on esterase activity extracted from the psocids, Liposcelis bostrychophila and L. entomophila

open access: yesJournal of Insect Science, 2004
The inhibition kinetics of dichlorvos on carboxylesterase and acetylcholinesterase (AChE) activity extracted from Liposcelis bostrychophila and L. entomophila (Psocoptera: Liposcelididae) were compared. The results showed that L.

Cutinase and Other Lipolytic Esterases Protect Bean Leaves from Infection by Rhizoctonia solani

open access: yesMolecular Plant-Microbe Interactions, 1998
The results describe a novel activity of fungal cutinase, the protection of bean leaves from disease. Development of web blight symptoms on bean leaves infected with Rhizoctonia solani (AG-1) was prevented in the presence of cutinase purified from ...

ProTides for Antiviral Activity Beyond Liver Cells

open access: yesChemistry – A European Journal, EarlyView.
A strategy for obtaining prodrugs of antiviral nucleotides with broad tissue activity is presented that relies on cycloalkyl or cycloalkylalkyl esters, improving uptake and esterase cleavage, and producing nanomolar inhibitors in kidney, colon, and lung cells.

Effects of Inoculants Producing Antifungal and Carboxylesterase Activities on Corn Silage and Its Shelf Life against Mold Contamination at Feed-Out Phase

open access: yesMicroorganisms, 2021
The present study aimed to investigate effects of dual-purpose inoculants (antifungal and carboxylesterase activities) not only on corn silage quality, but also its shelf life against mold contamination at feed-out phase.

A Simulation Study of Inhibition Assay With Theophylline on the Enzymatic Hydrolysis of p‐Nitrophenyl Phosphate With Alkaline Phosphatase in a Continuous Mode of Electrophoretically Mediated Microanalysis

open access: yesELECTROPHORESIS, EarlyView.
Inhibition assays in in‐capillary continuous enzymatic reaction were simulated using a MATLAB matrix. The enzymatic hydrolysis of p‐nitrophenyl phosphate (S) with alkaline phosphatase (ALP) was adopted as a model enzymatic reaction, where theophylline (I) was used as a model inhibitor.
