Question

G proteins are enzymes that bind and hydrolyze GTP to GDP. They are regulated by associated proteins that induce the binding of GTP and are called ____________ and that induce the hydrolysis of GTP to GDP and are called ___________.

Answer 1

Step-by-step explanation:

(A) Heterotrimeric G-proteins are composed of three distinct subunits (α, β, and γ). Receptor activation causes the binding of the G-protein and the α subunit to exchange GDP for GTP, leading (more...) The second class of GTP-binding proteins are monomeric G-proteins (also called small G-proteins).
