Thiols in catalase and SOD

[Chris Evelo]

Hello,

I am trying to find information on the presence of thiol groups in SOD
and catalase.

- Do those enzymes contain thiol groups that are important for activity
(and thus would loose activity if they were blocked)?
- Do those enzymes contain thiol groups on the outside that would lead
to crosslinking under strong oxidative conditions?

Any help appreciated,
