WebJun 13, 2024 · A T4 mediated survival-coupled mutagenesis approach was proposed. When polyhydroxybutyrate (PHB)-producing E. coli with T4 DNA ligase expressed in vivo was subjected to ionizing radiation, mutants with improved PHB production were acquired quickly owing to a large viable mutant library generated. WebT4 polynucleotide kinase catalyzes the transfer of the terminal phosphate group of ATP to the 5′-hydroxyl terminus of DNA or RNA. It also can catalyze the exchange of 5′-terminal phosphate groups. In contrast to the wild type E. coli enzyme, this phage derivative lacks 3′-phosphatase activity. The assay time is 30 minutes and volume ...
