چکیده
A derivative of Bacillus subtilis strain 168 sensitive to defective bacteriophages PBSX and PBSZ has been isolated. This particular strain, RUB824, carries the genetic information for defective bacteriophage PBSX.

Prophage mutation causing heat inducibility of defective Bacillus subtilis bacteriophage PBSX.
A mutant of Bacillus subtilis 168 has been isolated in which the defective phage PBSX was heat inducible, whereas another phage, phi105, was not so induced. A culture of the mutant grown at 30 degrees C, when shifted to 45 degrees C, began to lyse after 45 min; cell viability began to decrease after 10 min. Heat-induced lysis of the mutant was prevented by chloramphenicol. DNA, RNA, protein, an...
متن کاملGenetic mapping of a defective bacteriophage on the chromosome of Bacillus subtilis 168.
A genetic marker responsible for the killing activity of PBSX, a defective phage carried by Bacillus subtilis 168, has been located on the bacterial chromosome. Two mutant strains of B. subtilis 168, which produced tailless phage particles upon mitomycin C induction, were shown to carry lesions, designated xtl-1 and xtl-2, which were linked by transformation and PBS1-mediated transduction to me...
متن کاملGenetic control of bacterial suicide: regulation of the induction of PBSX in Bacillus subtilis.
PBSX is a phage-like bacteriocin (phibacin) of Bacillus subtilis 168. Bacteria carrying the PBSX genome are induced by DNA-damaging agents to lyse and produce PBSX particles. The particles cannot propagate the PBSX genome. The particles produced by this suicidal response kill strains nonlysogenic for PBSX. A 5.2-kb region which controls the induction of PBSX has been sequenced. The genes identi...
متن کاملLysis genes of the Bacillus subtilis defective prophage PBSX.
Four genes identified within the late operon of PBSX show characteristics expected of a host cell lysis system; they are xepA, encoding an exported protein; xhlA, encoding a putative membrane-associated protein; xhlB, encoding a putative holin; and xlyA, encoding a putative endolysin. In this work, we have assessed the contribution of each gene to host cell lysis by expressing the four genes in...
متن کاملAbortive infection of sporulating Bacillus subtilis 168 by phi 2 bacteriophage.
Bacteriophage phi2 is unable to replicate in Bacillus subtilis 168. Although some phage deoxyribonucleic acid (DNA) synthesis can occur, the DNA made is not biologically active and sedimentation analysis reveals that it is smaller in size than that of mature DNA or DNA isolated from phi2-infected permissive hosts. Messenger ribonucleic acid hybridizable with phi2 DNA is also synthesized in phi2...
