= Arginine finger
{wiki=Arginine_finger}
The term "arginine finger" is primarily used in the context of biochemistry and molecular biology, particularly in relation to proteins and enzymes. It refers to a specific structural motif that involves the amino acid arginine. This motif is often found in proteins that interact with nucleic acids, such as DNA or RNA. In many cases, the arginine finger plays a crucial role in the binding of the protein to nucleic acids, stabilizing the complex or facilitating enzymatic activity.
