Four chemoreceptors in Escherichia coli mediate responses to chemicals in the environment. The receptors self-associate and localize to the cell poles. This aggregation implies that interactions among receptors are important parameters of signal processing during chemotaxis. We examined this phenomenon using a receptor-coupled in vitro assay of CheA kinase activity. The ability of homogeneous p...
Substrates containing a P3 aspartic residue are in general cleaved poorly by thrombin. This may be partly due to an unfavourable interaction between the P3 aspartate and Glu192 in the active site of thrombin. In Protein C activation and perhaps also thrombin receptor cleavage, binding of ligands at the anion-binding exosite of thrombin seems to improve the activity of thrombin with substrates c...
The cannabinoid receptors, CB1 and CB2, are members of the G-protein coupled receptor family and share many of this family's structural features. A highly conserved aspartic acid residue in the second transmembrane domain of G-protein coupled receptors has been shown for many of these receptors to be functionally important for agonist binding and/or G-protein coupling. To determine whether this...
BACKGROUND AND PURPOSE Previous studies reported that Tat-NR2B9c, a peptide disrupting the N-methyl-d-aspartate receptor-postsynaptic density protein-95 interaction, reduced ischemic damage in the acute phase after stroke. However, its effect in the subacute phase is unknown. The aim of this study is to determine whether disrupting the N-methyl-d-aspartate receptor-postsynaptic density protein-...
A specific set of molecules including glutamate receptors is targeted to the postsynaptic specialization of excitatory synapses in the brain, gathering in a structure known as the postsynaptic density (PSD). Synaptic targeting of glutamate receptors depends on interactions between the C-terminal tails of receptor subunits and specific PDZ domain-containing scaffold proteins in the PSD. These sc...
The amino terminus of the Salmonella typhimurium aspartate receptor has been identified as formylmethionine by mass spectral analysis of the amino-terminal tryptic peptide. Purification and analysis of the blocked amino-terminal peptide was facilitated by the use of a mutant aspartate receptor which has a cysteine residue at position 3. The sequence of this peptide confirms the translational st...
