NASA's Busload of Science
Dan Charles
<jats:p>For 30 years, the shuttle has been the main ticket into space for NASA astronauts. But it has also delivered—and fixed—massive observatories and served as an orbiting laboratory. As the program ends, what is its scientific legacy?</jats:p>

The Highs and Lows of Shuttle Science
Dan Charles
<jats:p> The contributions of the shuttle to science have come in many flavors and at an irregular pace. <jats:italic>Science</jats:italic> has created a timeline of shuttle science missions. </jats:p>

Response to Comment on “The Mechanism for Activation of GTP Hydrolysis on the Ribosomeâ€
Rebecca M. Voorhees; T. Martin Schmeing; Ann C. Kelley; V. Ramakrishnan
<jats:p> Our report of the crystal structure of elongation factor Tu (EF-Tu) and aminoacyl–transfer RNA bound to the ribosome with a guanosine triphosphate (GTP) analog included a proposed mechanism of GTP hydrolysis by EF-Tu involving histidine-84. Liljas <jats:italic>et al</jats:italic> . summarize experimental evidence against this mechanism and propose a substrate-assisted catalytic model. However, these experiments and the model are also problematic. Further study is required to definitively determine the mechanism of GTP hydrolysis by EF-Tu. </jats:p>

Comment on “The Mechanism for Activation of GTP Hydrolysis on the Ribosomeâ€
Anders Liljas; Måns Ehrenberg; Johan Åqvist
<jats:p> Voorhees <jats:italic>et al</jats:italic> . (Reports, 5 November 2010, p. 835) determined the structure of elongation factor Tu (EF-Tu) and aminoacyl–transfer RNA bound to the ribosome with a guanosine triphosphate (GTP) analog. However, their identification of histidine-84 of EF-Tu as deprotonating the catalytic water molecule is problematic in relation to their atomic structure; the terminal phosphate of GTP is more likely to be the proper proton acceptor. </jats:p>
