	Excitatory postsynaptic potential - Wikipedia, the free encyclopedia
		In neuroscience, an excitatory postsynaptic potential (EPSP) is a temporary increase in postsynaptic membrane potential caused by the flow of positively charged ions into the postsynaptic cell.
		Larger EPSPs result in greater membrane depolarization and thus increase the likelihood that the postsynaptic cell reaches the threshold for firing an action potential.
		The neurotransmitter most often associated with EPSPs is the amino acid glutamate, and is the main excitatory neurotransmitter in the central nervous system.

	Glyphosate-tolerant 5-enolpyruvyl-3-phosphoshikimate synthases - Patent 5310667
		If a variant of EPSP synthase could be identified that had a high K.sub.i for glyphosate and a lower K.sub.m for PEP than the current variant, it would enhance the ability to achieve glyphosate tolerance in plant species or plant tissues where it is difficult to engineer a high level of gene expression.
		The EPSP synthase clone is then altered by oligonucleotide mutagenesis to insert the DNA substitution necessary to result in the alanine for glycine substitution in the first conserved amino acid sequence and an aspartic acid for glycine substitution in a second conserved amino acid sequence as previously described.
		The DNA was hybridized with a nick-translated EPSP synthase sequence from pMON9531 in a Southern blot procedure.

	Title of Invention: Glyphosate-tolerant 5-enolpyruv yl-3-phosphoshikimate synthase
		The glyphosate-tolerant EPSP synthases are prepared by substituting an alanine residue for a glycine residue in a conserved sequence found between positions 80 and 120 in the mature wild-type EPSP synthase.
		The nucleotide sequence for the mutant E. coli EPSP synthase aroA gene was determined by the method of Sanger (1977) and the corresponding amino acid sequence for the encoded EPSP synthase deduced therefrom.
		Hence, for purposes of the present invention glyphosate-tolerant EPSP synthase polypeptides produced by substituting an alanine for the second glycine in a sequence homologous to the sequence (-L-G-N-A-G-T-A-) located between positions 80 and 120 is considered an equivalent of the present discovery and therefore within the scope of the invention.

		EPSPs were recorded from CA1 neurons in rat hippocampal brain slices in response to Schaffer-collateral fiber stimulation.
		EPSPs were depressed to comparable levels by TTX (60 nM) or lowered stim, but facilitation was not changed, indicating a simple failure of axonal conduction.
		Fiber volley and EPSP amplitudes were measured from peak negative voltage to baseline (minimum-to-baseline) or alternatively, their initial slopes were measured between 20% and 80% of minimum.

	EPSP Synthase
		EPSP synthase was first purified as described by Lewendon and Coggins (20), but the method has since been improved through the use of a better vector employing the T7 promotor in E.
		In the forward direction, EPSP synthase can be coupled with chorismate synthase, the enzyme in the Shikimate pathway which converts EPSP to chorismate; as EPSP synthase produces EPSP, chorsimate synthase can convert EPSP to chorismate which can be detected at 275 nm (20).
		Since EPSP synthase can also proceed in the reverse direction, activity can also be assayed with coupling to pyruvate kinase and lactate dehydrogenase which oxidize NADH in the breakdown of pyruvate, allowing the detection of NADH loss at 340 nm which corresponds to pyruvate evolution by EPSP synthase (20).
