protein folding
Let an agent explain protein folding and its principles, relay the roles of chaperones and cellular compartments, describe misfolding diseases and folding prediction with attribution, and distinguish folding from synthesis and degradation.
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 protein folding and its principles, relay the roles of chaperones and cellular compartments, describe misfolding diseases and folding prediction with attribution, and distinguish folding from synthesis and degradation.
The process by which a polypeptide chain acquires its functional three-dimensional structure, driven by the amino acid sequence and interactions with water, and assisted in cells by chaperones and folding enzymes, including de novo folding of new chains, folding in the endoplasmic reticulum, refolding after stress and specialised pathways such as chaperonin-assisted tubulin folding; misfolding underlies diseases such as Alzheimer and prion diseases, and folding prediction has been transformed by computational methods.
What it is for: Producing functional protein structures.
It can be explain principles and pathways; relay chaperone roles; describe misfolding diseases; describe structure prediction.
Distinguishing features
Sequence determines structure
Energy landscape
Chaperone assistance
Misfolding diseases
What it looks like
Not visible; structures shown as ribbon models and folding landscapes in diagrams.
Physical character
folding times: microseconds to minutes range - by protein
How it is recognised
Chain acquiring three-dimensional structure
Spontaneous and chaperone-assisted
Protein synthesis makes the chain; degradation removes it; folding shapes it

- How should structure databases be linked?
- The registry entry has merged aliases naming Gene Ontology subprocesses; should they be split off?
