RecA

RecA is a protein found in bacteria that plays a crucial role in repairing DNA and helping bacteria survive stressful conditions. When DNA is damaged or needs to be exchanged, RecA binds to single-stranded DNA and forms a filament. This filament searches for matching sequences within the DNA, facilitating homologous recombination—a process that repairs breaks or exchanges genetic information. In essence, RecA acts as a DNA facilitator, ensuring genetic stability and adaptability in bacteria, which can also influence their ability to develop resistance to antibiotics.
