We found statistically significant correlations between increased resistance to 5-fluorocytosine and higher enzymatic activity of alkaline phosphatase, chymotrypsin, and alpha-glucosidase; increased resistance to fluconazole and higher enzymatic activity of esterase
and beta-glucosidase as well as increased susceptibility to ketoconazole and higher enzymatic activity of cystine arylamidase; increased susceptibility to fluconazole and higher enzymatic activity of mannosidase.
The increased level of esterases
in phosphine tolerant populations as compared to susceptible population has pointed some correlation between esterase
activities and phosphine tolerance.
The urine strip test reaction for leucocytes is based on the action of leucocyte esterase
in catalysing the hydrolysis of an ester of indolecarboxylic acid.
Regioselective deacetylation of cellulose acetates by acetyl xylan esterases
of different CE-families.
Bacillus subtilis KPA-1 was used in present study for esterase
production which was isolated from farm soil samples by enrichment culture technique.
Specific inhibitor tests for the biochemical and functional classification of esterases
by PAGE have distinguished carboxylesterases (Est-2, Est-3, Est-5, Est-6, Est-7, Est-8, Est-9, Est-10, and Est-16 isozymes) and acetylesterases (Est-4, Est-11, Est-12, Est-13, Est14, Est-15 isozymes) in grapes (ORASMO et al.
We measured the response of 3 detoxifying enzyme systems: general esterase
(EST), glutathione S-transferase (GST), and cytochrome P450 monooxygenase (P450).
The activity of esterases
in the gut was reduced in chlorpyrifos exposed termite worker, whereas proteases and cellulases in these workers remained non- significant with their control treatments.
from lactobacilli have been characterized, but esterase
production by L.
In order to obtain indirect information about the existence and intensity of genetic exchange between different regions and about the presence of insecticide resistance, the purpose of the current research is to determine the variability in esterase
activity in greenbug populations collected from very contrasting regions of Argentina and Chile in autumn and spring since 1987.
Furthermore, because Calcein-AM test results could be influenced by changes in esterase
activity, DC extracts, as well pure harpagoside were tested for a possible inhibition of this enzyme.
are enzymes which catalyse the hydrolytic breakdown of ester bonds.
