Bacteriophage T7, Gp4, DNA primase/helicase, N-terminal (IPR013237)

Short name: Phage_T7_Gp4_N

Overlapping homologous superfamilies


Domain relationships



This entry is represented by bacteriophage T7 Gp4. The characteristics of the protein distribution suggest prophage matches in addition to the phage matches.

This entry represents a zinc binding domain found in the N-terminal region of the bacteriophage T7 Gp4 and P4 alpha protein. P4 is a multifunctional protein with origin recognition, helicase and primase activities [PMID: 8253092, PMID: 9185573, PMID: 10892646].
