Sex-dependent differences in the activities of acetylsalicylic acid-esterases in mouse kidneys

open access: yesBrazilian Journal of Medical and Biological Research, 1999
Acetylsalicylic acid (ASA), the most used drug worldwide, is hydrolyzed to salicylic acid and acetate by esterases present in tissues of several species including humans. Sex differences in drug metabolism by rodent liver are documented in the literature.

Detection and characterization of esterase isozyme by disc gel electrophoresis using inhibitors [PDF]

open access: yes, 1982
The non-specific esterases include different types of esterases,, acetyl, aryl, carboxyl and cholin esterases. These forms are identified on the basis of their differential activity towards various inorganic inhibitors (Holmes and Master, 1968 ...

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.
