Phenotypes of a mutant
drastically reduced survival of mature dormant spores after exposure to ultrahigh vacuum desiccation and ionizing radiation that induce single strand (ss) DNA nicks and double-strand breaks (DSBs) [Pubmed|24285298]
''[[protein|recO]] [[protein|recJ]]'' double mutants are extremely sensitive against DNA damaging agents [Pubmed|26001966]
''[[protein|recO]] [[protein|dprA]]'' double mutants have a strongly reduced chromosomal transformation rate [Pubmed|23779106,22373918]
''[[protein|recO]] [[protein|addA]]-[[protein|addB]]'' double mutants are extremely sensitive against DNA damaging agents [Pubmed|26001966]

The protein
Catalyzed reaction/ biological activity
provides [[protein|RecA]] access to ssDNA during chromosomal transformation (together with [[protein|DprA]]) [Pubmed|22373918]
catalyzes annealing of [[protein|SsbA]] or [[protein|SsbA]]/[[protein|SsbB]] coated ssDNAs to allow the formation of DNA duplexes with tails during plasmid transformation [Pubmed|22373918]
required for the formation of [[protein|RecA]] DNA repair centers (together with [[protein|RecR]]) [Pubmed|24891441]
provides [[protein|RecA]] access to ssDNA during chromosomal transformation (together with [[protein|DprA]]) [Pubmed|22373918]
catalyzes annealing of [[protein|SsbA]] or [[protein|SsbA]]/[[protein|SsbB]] coated ssDNAs to allow the formation of DNA duplexes with tails during plasmid transformation [Pubmed|22373918]
required for the formation of [[protein|RecA]] DNA repair centers (together with [[protein|RecR]]) [Pubmed|24891441]
anneals [[protein|SsbA]]- or [[protein|SsbB]]-coated complementary strands of transfecting SPP1 phage DNA, yielding tailed SPP1 duplex intermediates [pubmed|31876108]
[[protein|DprA]], [[protein|RecO]] or viral single strand annealing G35P protein, may catalyze the annealing of complete linear phage genomes with redundant regions at the ends of the molecule, alone or with the help of an exonuclease, to produce a circular unit-length duplex viral genome ready to initiate replication [pubmed|31876108]
The protein
Protein family
recO family (according to Swiss-Prot)
recO family (single member, according to UniProt)
The protein
[SW|Interactions]
[[protein|SsbA]] (bound to ssDNA) -[[protein|RecO]], this helps to dislodge [[protein|SsbA]] and [[protein|SsbB]] from ssDNA [Pubmed|21170359,22373918]
[[protein|RecR]]-[[protein|RecO]], [[protein|RecR]]:[[protein|RecO]] molecular ratio of 2:1 (as judged from other bacteria such as ''E. coli'' and ''Deinococcus radiodurans'') [Pubmed|17581636]
