enzyme renaturation

[dowdeswm at meena.cc.uregina.ca]

I need specific examples of enzymes which undergo renaturation.  If anyone
has any information please provide the name of the enzyme, where it is found,
its substrate, conditions which cause denaturation, and conditions which
cause renaturation.  Also if possible please specify whether the procedure
will occur when the enzyme is isolated in a test tube or if chaperones
are needed

Thanks for any help
