Sliding-clamp-loader large subunit (also known as Gp44) from Bacteriophage T4 forms the sliding-clamp-loader together with the small subunit. These are members of the AAA+ superfamily of ATPases which form pentameric complexes that load sliding DNA clamps onto the DNA, key for processive chromosomal replication [1,2]. This entry represents the AAA+ ATPase lid domain.	Domain
