Electrophoretic characterization of esterase‐19 (ES‐19), a new arylesterase of the house mouse (Mus musculus)

Abstract
Esterase‐19 (ES‐19) of the house mouse, following specific visualization in electrophoretic and isoelectric focusing gels, is described. A list of diagnostic features was compiled including substrate specificity, inhibition and activation characteristics, temporal and spatial patterns of expression, distribution among laboratory and wild mouse strains. ES‐19 was classified as arylesterase (E.C. 3.1.1.2) and compared with ES‐16 and ES‐25, two other mouse arylesterases. Homology with brain esterases of rat, guinea pig, rabbit and man was found, and a uniform disegnation “arylesterase I” is proposed.
