Protein: DNA ligase (EC 6.5.1.1) (Polydeoxyribonucleotide synthase [ATP]) (P00970)
Organism: Enterobacteria phage T4 (Bacteriophage T4)
Function: DNA ligase, which is expressed in the early stage of lytic development, has been implicated in T4 DNA synthesis and genetic recombination. It may also play a role in T4 DNA repair.
