Structure of the Regulatory Complex of Escherichia coli III Glc with Glycerol Kinase
Abstract
The phosphocarrier protein III Glc is an integral component of the bacterial phosphotransferase (PTS) system. Unphosphorylated III Glc inhibits non-PTS carbohydrate transport systems by binding to diverse target proteins. The crystal structure at 2.6 Å resolution of one of the targets, glycerol kinase (GK), in complex with unphosphorylated III Glc , glycerol, and adenosine diphosphate was determined. GK contains a region that is topologically identical to the adenosine triphosphate binding domains of hexokinase, the 70-kD heat shock cognate, and actin. III Glc binds far from the catalytic site of GK, indicating that long-range conformational changes mediate the inhibition of GK by III Glc . GK and III Glc are bound by hydrophobic and electrostatic interactions, with only one hydrogen bond involving an uncharged group. The phosphorylation site of III Glc , His 90 , is buried in a hydrophobic environment formed by the active site region of III Glc and a 3 10 helix of GK, suggesting that phosphorylation prevents III Glc binding to GK by directly disrupting protein-protein interactions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
