Abstract:
The activity of tetralysine endopeptidase was examined with cell-free extracts of Escherichia coli AJ005. The peptidase activity of cell-free extracts increased as the concentration became higher, and reached its maximum at about 30 mg protein/ml. The peptidase activity was stable and maintained most of its activity throughout a 5 h period of observation during incubation at 35 degrees C.
