The reason for the GTPase activity of G proteins to be crucial for the functioning of a cell needs to be explained. A theory for G proteins to be not evolved in the hydrolysis of GTP as a catalyst needs to be proposed. Concept introduction: GTPase activities are performed by the GTPases which are the families of hydrolase enzymes. G proteins are the kind of proteins which act as molecular switches inside the cells. They transmit signals from outside to interior.

Biochemistry Please help. Thank you What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
