title: Escherichia coli protein X is the recA gene product.
abstract: Escherichia coli protein X is known to be made in large amounts following DNA damage or inhibition of DNA replication. We have shown that it is identical to the recA gene product by partial proteolytic digestion of the radiochemically pure proteins and analysis by electrophoresis on polyacrylamide-sodium dodecyl sulfate gels.
