CC   -!- FUNCTION: Forms the sliding-clamp-loader together with the small
CC       subunit. The clamp loader holds the clamp in an open conformation and
CC       places it onto the DNA. {ECO:0000255|HAMAP-Rule:MF_04163}.
CC   -!- SUBUNIT: The sliding-clamp-loader consists of 4 large subunits and 1
CC       small subunit. Interacts with the sliding clamp; this interaction
CC       allows the sliding-clamp-loader to open the sliding clamp. Part of the
CC       replicase complex that includes the DNA polymerase, the polymerase
CC       clamp, the clamp loader complex, the single-stranded DNA binding
CC       protein, the primase, the helicase and the helicase assembly factor.
CC       {ECO:0000255|HAMAP-Rule:MF_04163}.
CC   -!- SIMILARITY: Belongs to the Tevenvirinae sliding-clamp-loader small
CC       subunit family. {ECO:0000255|HAMAP-Rule:MF_04163}.
