Ultrahigh-Throughput Microfluidic Droplet Screening of Metagenomic Libraries for Esterases and Kemp Eliminases
… first reported functional metagenomic screen for esterases in droplets. Over 30 million droplets were sorted, amounting to 10× coverage of a metagenomic library consisting of over one million members; making this the largest esterase screen performed to date. Twelve clones encoding thirteen novel …

A cytochemical and biochemical study of acid hydrolases in developing plant cells, with particular reference to non-specific esterases
… LB salt, a biochemical study of non-specific esterases extracted from broad bean root tips, has shown that these enzymes have an estimated Km of 0.07 mM, a pH optimum of 5.5 and that they lose substantial activity when dialysed against distilled water as opposed to 5mM magnesium chloride and …

COMPARATIVE TOXICOLOGY OF LIPOSCELIS ENTOMOPHILA AND L. BOSTRYCHOPHILA IN RELATION TO THEIR MANAGEMENT
… effective insecticide against L. bostrychophila. Esterases from L. bostrychophila had a significantly higher specific activity towards ?-naphthyl acetate than those from L. entomophila. Of the various inhibitors tested, dichlorovos was found to be the most potent whilst the carbamate inhibitors …

Studies on the Formulation of Topical Corticosteroids
… were compared with their 21-isomers using esterases from hog liver and mouse skin homogenates. The results showed that the 21-esters were very sensitive to the esterases. Based on the quantitative data on the decomposition of these corticosteroids, it was clearly shown that the …

Identifying mechanisms of pyrethroid resistance in the navel orangeworm and novel methods of control
… P450 monooxygenases (P450s) and carboxylesterases (COEs). In the first chapter of my dissertation, I investigated the role of all P450s in the CYP3 and CYP4 clans associated with metabolism of xenobiotics in A. transitella through a comparative analysis using a susceptible population …

Isozyme patterns of selected isolates of Pholiota in the stirps "Adiposa"
… general protein patterns and zyrnograms of esterases, (alphanaphthylamidases), phenoloxidases (laccases and tyrosinases), and peroxidases on polyacrylamide gels. Harvesting of different isolates for protein extraction was carried out at comparable stages of development using dry weight …

Protein polymorphism in northern populations of field mice (Apodemus sylvaticus L.)
… migrating protein fraction in striated muscle. Esterases: Most esterase fractions were found to be nonspecific carboxylesterases. Each tissue has its own esterase pattern, but also shares fractions with other tissues. The physicochemical tests, breeding, ontogenetic and population data make it …

Evaluation of Surface Acetylated Bacterial Cellulose for Antibacterial Wound Dressing Applications
… were hypothesized to be cleaved by bacterial esterases or other hydrolytic enzymes such that acetic acid, a well-known antibacterial compound, will be produced leading to the death of the bacterial cells. Surface acetylation was confirmed via FTIR and its effect on the morphology of bacterial …

Fluorogenic probes for live-cell imaging of biomolecules
… groups until entry into a cell, where endogenous esterases catalyze the hydrolysis of esters, generating fluorescence. The susceptibility of masking groups to spontaneous hydrolysis is a major limitation of these probes. Previous attempts to address this problem have incorporated auto-immolative …
