| Abstract |
The effect of bacteriophage SPO1 infection of Bacillus subtilis and a deoxyribonucleic acid (DNA) polymerase-deficient (pol(-)) mutant of this microorganism on the synthesis of DNA has been examined. Soon after infection, the incorporation of deoxyribonucleoside triphosphates into acid-insoluble material by cell lysates was greatly reduced. This inhibition of host DNA synthesis was not a result of host chromosome degradation nor did it appear to be due to the induction of thymidine triphosphate nucleotidohydrolase. Examination of the host chromosome for genetic linkage throughout the lytic cycle indicated that no extensive degradation occurred. After the inhibition of host DNA synthesis, a new polymerase activity arose which directed the synthesis of phage DNA. This new activity required deoxyribonucleoside triphosphates as substrates, Mg(2+) ions, and a sulfhydryl reducing agent, and it was stimulated in the presence of adenosine triphosphate. The phage DNA polymerase, like that of its host, was associated with a fast-sedimenting cell membrane complex. The pol(-) mutation had no effect on the synthesis of phage DNA or production of mature phage particles. |

The YP address was taken from the Evoli phage in GenBank. The YP address was searched for in UniProt for the accession number. The accession number was searched in Quick Go. This made sure that the gene had not been annotated previously.This is a direct annotation. The GO ID was determined from searching for DNA polymerase in Quick Go. DNA polymerase is an enzyme that aids in DNA synthesis. |
