This structure’s activity is mediated by eIF2 in a process (10[1])that hydrolyzes GTP. EF-Tu cycles on and (10[1])off this (-5[1])structure as it catalyzes a processive (10[1])reaction. One substrate this structure binds (10[1])contains an acceptor stem and a (10[1])CCA (10[3])tail. In prokaryotes, this structure binds to (10[1])the (10[2])purine-rich (10[2])Shine-Dalgarno (10[5])sequence. (10[1])In (10[3])eukaryotes, this (10[1])structure that contains E, P, and (10[1]-5[1])A (10[3]-5[1])sites is made (10[3])up (10[1])of (10[3]-5[1])small (10[1])40S and large (10[1])60S (10[4])subunits. (10[1])tRNAs (10[1])containing (10[1])anti-codons are added to polypeptide chains in this (10[2])structure that (10[1])performs (10[3]-5[1])translation.For 10 points, name (10[1])these macromolecular complexes that take in mRNA to conduct protein (10[1])synthesis.
