By the description of the function of tet(34) - ARO:3002870, it does not interact with tetracyclines or their derivates, which the tetracycline inactivation enzyme are supposed to do - ARO:3000036.
So, tet(34) confers resistance to tetracyclines but it is not an enzyme acting on them. The the parent term ARO:3000036 does not really fit tet(34), does it?
