One enzyme which I think meets your requirements is lysyl oxidase (protein
lysine 6-oxidase, EC 1.4.3.13), its a secreted enzyme which is responsible for
initiating crosslinking in collagen and elastin by oxidizing specific lysine
residues. This enzyme is recoverable from 8M urea, and is active in a test
tube.
For further information see:
J Biol Chem 1992, 267, 8666
Methods in Enzymology 1982, 82, 305-319
I hope this may be some use.

I need a specific example of an enzyme that will denature and undergo
renaturation. If anyone can help please provide the name of the enzyme,
where it is found and what it does, what conditions cause denaturation,
and what conditions cause renaturation. Also please specify if the
renaturation can occur when the enzyme is isolated in a test tube, or if
chaperones are needed to obtain the correct tertiary structure.
Thanks for any help you can provide.
