DnaB helicase
From Wikipedia, the free encyclopedia
- The correct title of this article is dnaB helicase. The initial letter is shown capitalized due to technical restrictions.
dnaB helicase is an enzyme in prokaryotes which holds open the replication fork during DNA replication. Initially when dnaB binds to dnaA, it is associated with dnaC, a negative regulator. After dnaC dissociates, dnaB binds dnaG.
In eukaryotes, helicase function is provided by the T antigen.
The dnaB helicase is the product of the dnaB gene. The helicase enzyme that is produced is a hexamer.
