The crystal structure of bovine mitochondrial elongation factor Tu (EF-Tu), in complex with GDP has been determined at a resolution of 1. 94 A.

Sixteen conserved water molecules, common to EF-Tu and other G-proteins in the GDP-binding site are, described. These water molecules create a network linking separated parts, of the binding pocket. Mitochondrial EF-Tu binds nucleotides less tightly, than prokaryotic EF-Tu possibly due to an increased mobility in regions, close to the GDP-binding site. The C-terminal extension of mitochondrial, EF-Tu has structural similarities with DNA recognising zinc fingers, suggesting that the extension may be involved in recognition of RNA.

CRYSTAL STRUCTURE OF MITOCHONDRIAL EF-TU IN COMPLEX WITH GDP

Overview

The crystal structure of bovine mitochondrial elongation factor Tu (EF-Tu) in complex with GDP has been determined at a resolution of 1. 94 A. The structure is similar to that of EF-Tu:GDP from Escherichia coli and Thermus aquaticus, but the orientation of the GDP-binding domain 1 is changed relative to domains 2 and 3. Sixteen conserved water molecules common to EF-Tu and other G-proteins in the GDP-binding site are described. These water molecules create a network linking separated parts of the binding pocket. Mitochondrial EF-Tu binds nucleotides less tightly than prokaryotic EF-Tu possibly due to an increased mobility in regions close to the GDP-binding site. The C-terminal extension of mitochondrial EF-Tu has structural similarities with DNA recognising zinc fingers suggesting that the extension may be involved in recognition of RNA.

About this Structure
