DnaG
Encyclopedia
DnaG is a bacterial primase
which synthesizes short RNA oligonucleotides during DNA replication. These RNA oligonucleotides serve as primers for DNA synthesis by bacterial DNA polymerase Pol III. On one of the two parental strands, called the lagging strand, the primase makes a primer every few kilobases. These primers serve a substrates for synthesis of Okazaki fragments.
DnaG associates with bacterial replicative helicase DnaB to perform its primase activity. About three DnaG primase proteins associate with each DnaB helicase.
