GRANT READ ON sys.prot

Hai, i want to give the a user the privilege read on sys.prot.
But it doesn´t work.

This is my sql-statement:
GRANT READ ON sys.prot to EJOT_LC

And this the error:

ORA-00942:table or view does not exist

Can somebody tell me what to do?
In the database the table prot doesn´t exist. But in another database the table doesn´t exist too, but it works.

Is prot a system-table? or something else?

I´m lucky about every information.

Thanks a lot!
