RecA

<p>RecA is a 38 <a href="/facts/Dalton_(unit)/IMATU3vf">kilodalton</a> <a href="/facts/Protein/Jxmagu3E">protein</a> essential for the repair and maintenance of <a href="/facts/DNA/nB89Iauz">DNA</a> in <a href="/facts/Bacteria/wC8xSCsU">bacteria</a>. Structural and functional homologs to RecA have been found in all kingdoms of life. RecA serves as an archetype for this class of homologous <a href="/facts/DNA_repair/hsURuYYq">DNA repair</a> proteins. The homologous protein is called <a href="/facts/RAD51/ml7klNxX">RAD51</a> in <a href="/facts/Eukaryotes/SkwyPLMA">eukaryotes</a> and <a href="/facts/RadA/0LQCnMwU">RadA</a> in <a href="/facts/Archaea/Adxh0aHw">archaea</a>.
</p><p>RecA has multiple activities, all related to DNA repair. In the bacterial <a href="/facts/SOS_response/LFrC6t6N">SOS response</a>, it functions as a co-<a href="/facts/Protease/G1ASdVat">protease</a> in the <a href="/facts/Autocatalytic/2eGCpunY">autocatalytic</a> cleavage of the <a href="/facts/LexA_repressor/jPC117wA">LexA repressor</a> and the <a href="/facts/Lambda_phage/z17FFUSW">λ</a> repressor.
