WebG proteins, also known as guanine nucleotide-binding proteins, are a family of proteins that act as molecular switches inside cells, and are involved in tran... The mechanism of GTPase activation varies among different GEFs. However, there are some similarities in how different GEFs alter the conformation of the G protein nucleotide-binding site. GTPases contain two loops called switch 1 and switch 2 that are situated on either side of the bound nucleotide. These regions and the phosphate-binding loop of the GTPase interact with the phosphates of the nucleotide and a coordinating magnesium ion to maintain high affinity binding … modify an existing qr code
