The methyl ester of the dipeptide that this amino acid forms with phenylalanine is the active ingredient of a namesake artificial sweetener.
In Alzheimer's disease, mutations of either one of two of these residues in presenilin-1 eliminates the protein's ability to interact with Notch. The condensation of this compound and carbamoyl phosphate is the first committed step of pyrimidine biosynthesis. P-type ATPases all catalyze the phosphorylation of this amino acid, whose namesake protease is encoded for by HIV's pol gene. The N-methyl derivative of this amino acid is the selective agonist for an ionotropic receptor blocked in a voltage-dependent fashion by magnesium. This compound hydrogen bonds to a histidine to form part of the catalytic triad of chymotrypsin. A cytosolic (*) transaminase converts this amino acid to oxaloacetate in a shuttle named for this malate and this compound. The methyl ester of the dipeptide that this amino acid forms with phenylalanine is the active ingredient of a namesake artificial sweetener. For 10 points, name this amino acid that like glutamate has an acidic side chain.
