The structure of rat cytosolic PEPCK in complex with phosphoglycolate and GDP

4-(2-HYDROXYETHYL)-1-PIPERAZINE ETHANESULFONIC ACID

Enzymes with lid-gated active sites must operate by an induced fit mechanism instead of conformational selection.

Flat mirror (vertical focusing); single crystal Si(111) bent monochromator (ho rizontal focusing)

Side scattering bent cube-root I-beam single crystal; asymmetric cut 4.965 degs

Phosphoenolpyruvate carboxykinase, cytosolic [GTP]

PEPCK-C, Phosphoenolpyruvate carboxylase
