Gene
Phenotypes of a mutant
strongly impaired genetic recombination [Pubmed|23779106]
''[[gene|recO]] [[gene|dprA]]'' double mutants have a strongly reduced chromosomal transformation rate [Pubmed|23779106,22373918]
strongly impaired genetic recombination [Pubmed|23779106]
''[[gene|recO]] [[gene|dprA]]'' double mutants have a strongly reduced chromosomal transformation rate [Pubmed|23779106,22373918]
loss of plasmid transformation [pubmed|30050509]
The protein
Catalyzed reaction/ biological activity
binds ssDNA, promotes displacement of [[protein|SsbA]] and [[protein|SsbB]] from ssDNA [Pubmed|23779106]
provides [[protein|RecA]] access to ssDNA during chromosomal transformation (together with [[protein|RecO]]) [Pubmed|22373918]
RecA-ATP in concert with [[protein|DprA]] and [[protein|SsbA]] catalyzes DNA strand exchange, with [[protein|SsbB]] as an accessory factor [Pubmed|25138221]

[[protein|RecA]]-ATP in concert with [[protein|DprA]] and [[protein|SsbA]] catalyzes DNA strand exchange, with [[protein|SsbB]] as an accessory factor [Pubmed|25138221]
the [[protein|SsbA]]-[[protein|DprA]] mediator loads [[protein|RecA]] onto any fragmented linear SPP1 ssDNA [pubmed|31876108]
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]
