In E. coli, what is the function of the DnaB enzyme?

0 votes

 

DnaB allows the newly synthesized strand to reanneal, re-forming complementary double-stranded DNA.

DnaB bends DNA and breaks hydrogen bonds in the A-T rich 13-mer region of oriC, creating an open complex, a short region where strands of the duplex are separated.

DnaB prevents reannealing of the separated strands, keeping them available to serve as templates for new DNA synthesis.

DnaB is a helicase protein that uses ATP energy to hydrolyze hydrogen bonds, which separates the DNA strands and unwinds the double helix.
