Summary
-
1.
Hfr, F + and RTF strains of E. coli produce an extracellular inhibitor of nitrogen mustard after-effect (NMAE) in NM-treated F --cells.
-
2.
The NMAE inhibiting factor is a non-dialyzable protein.
-
3.
The NMAE inhibiting factor is inactive in F -rec- and F -uvr--cells treated with NM.
