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 ... WebThe mutant T4 DNA ligase cannot perform the first step of the ligation reaction since the mutated lysine residue is in the active site where AMP is attached to form ligase adenylate. In the presence of a low concentration of ATP (10 µM) and Mg2+ (10 mM), a combination of a high concentration of T4 WT DNA songs with radio in lyrics
