In molecular biology, an arginine finger is an amino acid residue of some enzymes.[1][2] Arginine fingers are often found in the protein superfamily of AAA+ ATPases, GTPases, and dUTPases, where they assist in the catalysis of the gamma phosphate or gamma and beta phosphates from ATP or GTP, which creates a release of energy which can be used to perform cellular work.[3][1][4][2] They are also found in GTPase-activating proteins (GAP).[5] Thus, they are essential for many forms of life, and are highly conserved.[3][1][6] Arginine fingers function through non-covalent interactions.[1] They may also assist in dimerization, and while they are found in a wide variety of enzymes, they are not ubiquitous.[7][8]
