Identification of novel esterase-active enzymes from hot environments by use of the host bacterium Thermus thermophilus

Frontiers in Microbiology, 2015
Functional metagenomic screening strategies, which are independent of known sequence information, can lead to the identification of truly novel genes and enzymes. Since E.

Lysozymes' esterase activity

FEBS Letters, 1983
A non‐specific esterase activity of hen lysozyme (c‐type) has previously been described: histidine was claimed to be involved in this activity. The present letter reports that a histidine‐less lysozyme from the duck egg‐white (c‐type) as well as a goose lysozyme (g‐type) possess such an esterase activity determined using p‐nitrophenylacetate.

Esterase Activity of Pepsin [PDF]

Nature, 1964
IT is known that many proteolytic enzymes—trypsin, chymotrypsin, thrombin, papain and others—hydrolyse peptide, amide and ester bonds. Pepsin, however, is generally believed to hydrolyse the peptide bonds only, without exhibiting the esterase activity1.

Purification and Biochemical Properties of Carboxylesterase from Saga Seeds (Adenanthera pavonina) [PDF]

Journal of Stress Physiology & Biochemistry, 2021
Carboxyl esterase (E.C.No.3.1.1.1) was partially purified from Adenanthera pavonina (Saga) using ammonium sulfate fractionation (0-60%) and DEAE (diethyl aminoethyl) ion exchange chromatography, the purified enzyme was characterized.

Computational Insights into the Catalytic Mechanism of Is‐PETase: An Enzyme Capable of Degrading Poly(ethylene) Terephthalate

Chemistry – A European Journal, Volume 28, Issue 70, December 15, 2022., 2022
The enzyme is‐PETase degrades poly(ethylene) terephthalate (PET) at mesophilic temperatures. This makes is‐PETase a promising candidate for the biodegradation of this common pollutant. The energy profile for the degradation of a PET substrate mimic by is‐PETase was calculated by using computational quantum‐mechanical/molecular mechanical methods, and ...

Arabidopsis SFAR4 is a novel GDSL-type esterase involved in fatty acid degradation and glucose tolerance

Botanical Studies, 2015
BackgroundSFARs (seed fatty acid reducers) belonging to the GDSL lipases/esterases family have been reported to reduce fatty acid storage and composition in mature Arabidopsis seeds.

Contribution of soil esterase to biodegradation of aliphatic polyester agricultural mulch film in cultivated soils

AMB Express, 2015
The relationship between degradation speed of soil-buried biodegradable polyester film in a farmland and the characteristics of the predominant polyester-degrading soil microorganisms and enzymes were investigated to determine the BP-degrading ability of

Prodrugs of the Archetypal Dynamin Inhibitor Bis‐T‐22

ChemMedChem, Volume 17, Issue 24, December 16, 2022., 2022
The Bis‐T series of compounds comprise some of the most potent inhibitors of dynamin GTPase activity yet reported, such as Bis‐T‐22 (2). The catechol moieties are believed to limit cell permeability, rendering these compounds largely inactive in cells.

Synthesis of Sitagliptin Intermediate by a Multi-Enzymatic Cascade System Using Lipase and Transaminase With Benzylamine as an Amino Donor

Frontiers in Bioengineering and Biotechnology, 2021
Herein, we report the development of a multi-enzyme cascade using transaminase (TA), esterase, aldehyde reductase (AHR), and formate dehydrogenase (FDH), using benzylamine as an amino donor to synthesize the industrially important compound sitagliptin ...

The acylated (AG) to unacylated (UAG) ghrelin ratio in esterase inhibitor‐treated blood is higher than previously described

Clinical Endocrinology, 2015
The acylated/unacylated ghrelin (AG/UAG) ratio has been reported to range from 0·02 to 0·3, suggesting biologically relevant independent regulation of each ghrelin isoform.
