examination of 4npo sensitivity of pro ( + ) transductants derived from proa ( - ) and prob ( - ) cells with p1 vir phage and pro ( + ) cells as donor and of pro ( + ) spontaneous revertants derived from those pro ( - ) cells suggested that 4npo-sensitive gene ( s ) should be on , or very close to , the proa and prob loci and that both products of proa and prob genes may be involved in the sensitivity of bacteria to 4npo .
