GO:1990077 primosome complex

Term Information

ID GO:1990077
Name primosome complex
Ontology Cellular Component
Definition Any of a family of protein complexes that form at the origin of replication or stalled replication forks and function in replication primer synthesis in all organisms. Early complexes initiate double-stranded DNA unwinding. The core unit consists of a replicative helicase and a primase. The helicase further unwinds the DNA and recruits the polymerase machinery. The primase synthesizes RNA primers that act as templates for complementary stand replication by the polymerase machinery. The primosome contains a number of associated proteins and protein complexes and contributes to the processes of replication initiation, lagging strand elongation, and replication restart.

ID Mapping

QuickGO maps between different identifier types by using a combination of mapping files provided by the databases, and using identifier cross-references supplied by UniProtKB.

If more than one identifier type needs to be used to map all required sequences, drag the selected databases to change the order in which identifiers are found.

Early complexes initiate double-stranded DNA unwinding. The core unit consists of a replicative helicase and a primase. The helicase further unwinds the DNA and recruits the polymerase machinery. The primase synthesizes RNA primers that act as templates for complementary stand replication by the polymerase machinery. The primosome contains a number of associated proteins and protein complexes and is part of the replication initiation process.
