FIG. 5.

Degradation of ¹²⁵I-labeled laminin (A) and ³⁵S-labeled extracellular matrix prepared from human lung NCI-H292 cells (B) by Pla⁺ or Pla⁻ recombinant E. coli in the presence of plasminogen and inhibitors of plasmin activity. (C) Plasmin activity associated with the E. coli cells or in PBS without added bacteria, measured with the chromogenic substrate. Bacteria were used at a concentration of 2 × 10⁹ cells/ml.
