Restoration Of Phage Growth On A Non-Permissive Host By Bypassing Transcription Termination Signals, Millicent Ronkainen
Honors College Capstone Experience/Thesis Projects
RNA polymerase is the central enzyme in all gene expression. The rpoCY75N mutation in the zinc-binding domain of the β’ subunit of E. coli RNA polymerase blocks a unique RNA-based mechanism of transcription antitermination utilized by bacteriophage HK022 and its relatives. Here, we describe the characterization of mutant phage, orc0368, which overcomes the rpoCY75N mutation. The orc0368 genome varies from the wild type phage genome by 4 single base pair mutations. Three of these mutations were not characterized because they occur in intergenic regions but the fourth was chosen for study because of its location between a series ...
