The relative activity of different fractions to the cell fragmentation. The assays were carried out in Tris–HCL buffer (pH 7.8, 50 mM) containing 20 mM KF, 1 mM SAM and induced cells or supernatant or cell debris of cell fragmentation at equal quantity for 1 h at 37 ℃. Relative values were based on catalytic ability of the disrupted cell suspension. Results are presented as the mean values and standard deviations of data from three replicates.
