esterase
Let an agent explain esterases and their classification and mechanisms, describe biological roles and applications, identify families and specific enzymes with sources, and support learning.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled
A hydrolase enzyme that splits esters into an acid and an alcohol by adding water, including carboxylesterases, lipases, phosphatases and phosphodiesterases acting on phosphoric esters, sulfatases, thioesterases, pectinesterases and tannases in plants and microbes, and engineered enzymes such as PETase that degrade plastic; esterases occur in all organisms, function in metabolism, signalling, digestion and detoxification, and are used in industry and biotechnology.
