Protein expression and activity. A SDS‒PAGE of recombinant depolymerase. Lane 1, protein marker; Lane 2, purified depolymerase dep1011. B Depolymerase activity against KP181. First, 50 ng of dep1011 or PBS was spotted on the lawn of KP181. C Bacterial sediment of wild-type strains and strains treated with depolymerase. 1, Bacterial sediment of B16; 2, bacterial sediment of B16 treated with depolymerase; 3, bacterial sediment of KP181; 4, bacterial sediment of KP181 treated with depolymerase.
