Structure and Function of G Proteins from Mammalian and Yeast Cells
A superfamily of GTP binding proteins consists of several families including (1) translational factors, (2) signal transducing G proteins, (3) protooncogenic ras proteins, and (4) other low-molecular-weight GTP binding proteins such as rho, sec (sec4, YPTl, etc.) and arf families. There are also other GTP-binding proteins such as tubulins and a group of metabolic GTP-binding proteins including succinate thiokinase and phosphoenolpyruvate carboxykinase, but they will not be discussed here.
