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.

Purpose and description

Let an agent explain what hydrolases are and how they are classified, relay nomenclature and database identifiers, place them among enzyme classes, and route detailed biochemical, industrial or clinical questions to the right resources.

A class of enzymes that catalyse the cleavage of a chemical bond by adding water, classified as EC 3 in the Enzyme Commission system and covering esterases, glycosidases, peptidases, lipases, nucleases and phosphatases; hydrolases digest food, recycle cell components and are used in detergents, food processing and diagnostics.

What it is for: Not for anything; a class of biological catalysts.

It can be explain the class and its subclasses; look up an enzyme by EC number; explain uses in digestion, industry and diagnostics; route mechanism and clinical questions.

Distinguishing features

Catalyse bond cleavage with water

EC class 3

Subclass follows the bond: ester, glycosidic, peptide, and others

Many are secreted digestive or lysosomal enzymes

What it looks like

Not visible; proteins characterised by activity assays and structures.

Physical character

EC subclasses: 13 subclasses - EC 3.1 to 3.13

optimum pH: 2-10 pH - by enzyme; pepsin acidic, trypsin alkaline

How it is recognised

EC number beginning with 3

Named by substrate with the suffix ase: lipase, protease, amylase

Transferases and oxidoreductases are other classes
