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 peptidases and their classification and mechanisms, describe biological roles and applications, identify families and specific enzymes with sources, and support learning.

An enzyme that catalyses the hydrolysis of peptide bonds in proteins and peptides, including endopeptidases that cut within chains and exopeptidases such as carboxypeptidases and aminopeptidases that remove terminal residues, classified by catalytic mechanism as serine, cysteine, aspartic, metallo and other types; peptidases digest food proteins, regulate cellular processes, build bacterial cell walls, and are drug targets and industrial enzymes.

What it is for: Enzymes that cleave peptide bonds.

It can be explain classification and mechanism; describe roles and applications; identify families; support learning.
