CC   -!- FUNCTION: Binds to DNA in a highly cooperative manner without
CC       pronounced sequence specificity. During synthesis of the single-
CC       stranded (progeny) viral DNA, prevents the conversion into the double-
CC       stranded replicative form. G5P is displaced by the capsid protein G8P
CC       during phage assembly on the inner bacterial membrane (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the inovirus G5P protein family. {ECO:0000305}.
