esterases

What he "forgot": methylation of 23S rRNA preventing binding of antibiotic and * gasp* inactivation of the antibiotic by enzymes such as esterases and glycosidase.

Determining the role of natural selection in maintaining enzyme polymorphisms, such as the fast/slow polymorphisms of alcohol dehydrogenase (which detoxifies environmental alcohol), superoxide dismutase (which catalyzes the removal of free oxygen radicals), or the esterases (which are involved in the detoxification of pesticides by many insects), became a primary focus of investigation with the goal of finding a selective basis for the enzyme variants in terms of differences in their physical and kinetic properties.

GRN1005 is a prodrug, which becomes activated in cells after it is cleaved by esterases to release active paclitaxel from the peptide.

DCFH-DA diffuses through the cell membrane and is hydrolyzed by intracellular esterases to nonfluorescent dichlorofluorescin (DCFH) that is rapidly oxidized to highly fluorescent dichlorofluorescein by ROS such as hydrogen peroxide
