Protein

Sliding-clamp-loader gp44 subunit

Gene

62

Organism
Enterobacteria phage T4 (Bacteriophage T4)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Experimental evidence at protein leveli

Functioni

Function as a sliding-clamp-loading ATPase enzyme during DNA replication. Required for elongation of primed templates by controlling the polymerase processivity. Progressive binding of ATPs triggers a conformational change in the complex that inhibits ATPase activity.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
