A [auth B], B [auth E], C, D | PF21328 | Sliding-clamp-loader large subunit, AAA+ ATPase lid domain (Gp44_lid) | Sliding-clamp-loader large subunit, AAA+ ATPase lid domain | 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 c ... | Domain |
A [auth B], B [auth E], C, D | PF21429 | Sliding-clamp-loader large subunit, C-terminal domain (Gp44_C) | Sliding-clamp-loader large subunit, C-terminal domain | This domain is found at the C-terminal end of Sliding-clamp-loader large subunit from Bacteriophage T4 (Gp44) and similar proteins predominantly found in tailed bacteriophages. Gp44 functions as an ATPase enzyme. It also contains an AAA module (Pfam: ... | Domain |
A [auth B], B [auth E], C, D | PF00004 | ATPase family associated with various cellular activities (AAA) (AAA) | ATPase family associated with various cellular activities (AAA) | AAA family proteins often perform chaperone-like functions that assist in the assembly, operation, or disassembly of protein complexes [2]. | Domain |
E [auth A] | PF16790 | Bacteriophage clamp loader A subunit (Phage_clamp_A) | Bacteriophage clamp loader A subunit | This is the A subunit of bacteriophage DNA clamp loader required for loading of sliding clamps onto chromosomal DNA. These clamps are involved in processivity of DNA replication [1]. | Domain |
F [auth G], G [auth H], H [auth F] | PF09116 | gp45 sliding clamp, C terminal (gp45-slide_C) | gp45 sliding clamp, C terminal | Members of this family are essential for the interaction of the gp45 sliding clamp with the corresponding polymerase. They adopt a DNA clamp fold, consisting of two alpha helices and two beta sheets - the fold is duplicated and has internal pseudo tw ... | Domain |
