===Crystal Structure of the Phage P4 Origin-Binding Domain===
+
[https://www.uniprot.org/uniprot/PRIM_BPP4 PRIM_BPP4] This protein acts as a DNA primase generating di- to pentaribonucleotides; the predominant product being the dimer pppApG. It complexes specifically to the P4 origin of replication (ori) and its cis replication region (crr). It also acts as a DNA helicase.
