Function
Catalyzes the hydrolysis of the amide bond of streptolidine lactam, thereby conferring streptothricin (ST) resistance. Can hydrolyze streptothricin-F and streptothricin-D. However, this strain is believed to be a ST nonproducer, which raises the possibility that its true role may not be its involvement in self-resistance to STs. May catalyze the hydrolysis of naturally occurring cyclic amide compounds that are structurally related to STs.
