SOLUTION STRUCTURE OF THE GUANINE NUCLEOTIDE EXCHANGE FACTOR DOMAIN FROM HUMAN ELONGATION FACTOR-ONE BETA, NMR, 20 STRUCTURES
Overview
BACKGROUND: In eukaryotic protein synthesis, the multi-subunit elongation, factor 1 (EF-1) plays an important role in ensuring the fidelity and, regulating the rate of translation. EF-1alpha, which transports the, aminoacyl tRNA to the ribosome, is a member of the G-protein superfamily., EF-1beta regulates the activity of EF-1alpha by catalyzing the exchange of, GDP for GTP and thereby regenerating the active form of EF-1alpha. The, structure of the bacterial analog of EF-1alpha, EF-Tu has been solved in, complex with its GDP exchange factor, EF-Ts. These structures indicate a, mechanism for GDP-GTP exchange in prokaryotes. Although there is good, sequence conservation between EF-1alpha and EF-Tu, there is essentially no, sequence similarity between EF-1beta and EF-Ts. We wished to ... [(full description)]
