DNA Helicase
DNA Helicase is a complex, 14 chain structure that unwinds DNA in replication by cleaving the hydrogen bonds between the complementary nucleotides at the replication fork. It is present in both prokaryotes and eukaryotes.
Function
By cleaving the hydrogen bonds between the complementary nucleotides at the , Helicase allows DNA polymerase to have access to each DNA strand in order to replicate each strand. Aside from its part in DNA replication, it also functions to unwind DNA in repair, transcription, and recombination.
Disease
Malfunctioning Helicase
Structural highlights
There are several ligands the various chains together. In various places throughout Helicase, a acts as a ligand.
