E. coli DNA Ligase

Category: Products & Services > Proteins, Enzymes, & Peptides > Enzymes > DNA⁄RNA Modifying Enzymes

E. coli DNA Ligase catalyzes the formation of phosphodiester bonds in the presence of β-NAD between double-stranded DNAs with 3´ hydroxyl and 5´ phosphate cohesive termini. Single-stranded nucleic acids are not substrates for this enzyme. Applications: Second-strand cDNA synthesis (1). T4 DNA Ligase alternative when blunt-end ligation is not required (2). Source: Purified from E. coli 594 (Su - ) bearing λ lysogen gt4lop-11 lig + S7 (3). Performance and Quality Testing: Endodeoxyribonuclease and 3´ and 5´ exodeoxyribonuclease assays; ligation efficiency tested. Unit Definition: One unit is the...
