A protein-replication complex that catalyses the initiation of synthesis of Okazaki fragments during discontinuous replication of DNA. It involves DNA primase and DNA helicase activities.
A protein complex, consisting mainly of DNA helicase and primase, that unwinds the DNA helix prior to replication and synthesizes RNA primer sequences.
A complex of two proteins, a primase and a helicase, that initiates RNA primers on the lagging DNA strand during DNA replication.
A protein complex involved in DNA replication.
A primosome is a complex of seven proteins: Dna G primase, Dna B helicase, Dna C helicase assistant, Dna T, Pri A, Pri B, and Pri C. The primosome creates RNA primers on single stranded DNA during DNA replication. The primosome is utilized once on the leading strand of DNA and repeatedly, initiating each Okazaki fragment, on the lagging DNA strand.
