CsrA

CsrA is a small protein found in bacteria that acts as a regulator, controlling how the bacteria express certain genes. It binds to specific messenger RNA molecules, influencing whether they are turned into proteins. By doing so, CsrA helps bacteria adapt to different environments, regulate their metabolism, and manage processes like movement and biofilm formation. It plays a key role in bacterial survival and behavior, making it an important factor in understanding how bacteria function and respond to their surroundings.
