Biochemical biomarkers of Glyphodes pyloalis Walker (Lepidoptera: Pyralidae) in exposure to TiO2 nanoparticles

open access: yesInvertebrate Survival Journal, 2014
Biochemical biomarkers and bioassays, due to their assumed immediate response after acute exposure of the organism to the stressor, are useful tools to gauging anthropogenic impacts. The toxicity of TiO2-nanoparticles (TiO2-NPs) on the Glyphodes pyloalis

Esterases and uses thereof

open access: yes, 2022
The present invention relates to novel esterase, more particularly to esterase variants having improved activity compared to the esterase of SEQ ID No 1 and the uses thereof for degrading polyester containing material, such as plastic products.

SUBCELLULAR LOCALIZATION OF RAT BRAIN ESTERASES

open access: yes, 1966
The localization and properties of soluble and bound esterases of subcellular fractions of rat brain have been investigated. Bound esterases were extracted with 1% Triton X-100 and separated by starch gel electrophoresis.

Lysozymes' esterase activity

open access: yesFEBS 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.

Molecular Marker to Identify Two Stingless Bee Species: Tetragonisca angustula and Tetragonisca fiebrigi (Hymenoptera, Meliponinae)

open access: yesSociobiology, 2014
Tetragonisca angustula and T. fiebrigi esterases were biochemically characterized by their inhibition pattern and thermostability. Workers of both species were collected from nests at the State University of Maringa. In T.

A Study of Rabbit Microsomal Esterases

open access: yes, 1973
1. The microsomal fraction of rabbit liver and kidney preparations (and probably intestinal mucosa) contained a high proportion of the total esterase activity of these organs. All the substrates used confirmed this conclusion. 2.
