Periplasmic space enzyme marker

Can anyone suggest an enzyme with an easy to assay activity which can
be used as a marker for the periplasm of E. coli OTHER than alkaline
phophatase, beta lactamase or ribonuclease??? We need to assay for
leakage from the periplasm and for technical reasons can not use any
of these standard enzyme markers. 

Many thanks.
