WebThe most common mutations are found at residue G12 in the P-loop and the catalytic residue Q61. The glycine to valine mutation at residue 12 renders the GTPase domain of Ras insensitive to inactivation by GAP and thus stuck in the "on state". Ras requires a GAP for inactivation as it is a relatively poor catalyst on its own, as opposed to other ... WebA mutation is a permanent change in an organism’s genetic material. Mutations occur naturally when cells divide. ... Plasmids often carry genes encoding enzymes capable of inactivating certain antibiotics.
