Editing Prochlorococcus (section)

==DNA recombination, repair and replication==

Marine ''Prochlorococcus'' [[cyanobacteria]] have several genes that function in DNA [[homologous recombination|recombination]],  [[DNA repair|repair]] and [[DNA replication|replication]].  These include the ''[[recBCD]]'' gene complex whose product, [[exonuclease]] V, functions in recombinational repair of DNA, and the ''umuCD'' gene complex whose product, [[DNA polymerase V]], functions in error-prone DNA replication.<ref name = Cassier-Chauvat2016>{{cite journal |vauthors=Cassier-Chauvat C, Veaudor T, Chauvat F |title=Comparative Genomics of DNA Recombination and Repair in Cyanobacteria: Biotechnological Implications |journal=Front Microbiol |volume=7 |pages=1809 |date=2016 |pmid=27881980 |pmc=5101192 |doi=10.3389/fmicb.2016.01809 |doi-access=free}}</ref> These cyanobacteria also have the gene ''lexA'' that regulates an [[SOS response]] system, probably a system like the well-studied ''E. coli'' SOS system that is employed in the response to [[DNA damage (naturally occurring)|DNA damage]].<ref name = Cassier-Chauvat2016/>
