Aspartate decarboxylase
Aspartate decarboxylase (PanD, ADC, EC 4.1.1.11) is the bacterial pyruvoyl-dependent enzyme converting L-aspartate to β-alanine, the committed step of pantothenate and coenzyme A biosynthesis.
Aspartate kinase
Aspartate kinase (aspartokinase, AK, EC 2.7.2.4) is the first committed, allosterically feedback-inhibited enzyme of aspartate-family amino acid biosynthesis (lysine, threonine, methionine, isoleucine) in microbes and plants, absent from animals.
Aspartate transaminase
Aspartate transaminase (AST, GOT), a PLP-dependent enzyme interconverting aspartate and alpha-ketoglutarate with oxaloacetate and glutamate; cytosolic and mitochondrial isoenzymes, malate-aspartate shuttle role, and standard serum liver-injury marker.
Aspartate-semialdehyde dehydrogenase
Aspartate-semialdehyde dehydrogenase (ASADH, EC 1.2.1.11, asd gene) is a dimeric NADPH-dependent enzyme converting aspartyl phosphate to aspartate-semialdehyde at the branch point of bacterial, plant, and fungal lysine and threonine/methionine biosynthesis.
Aspartic acid

Aspartoacylase
Aspartoacylase (ASPA, ACY2) is a zinc carboxypeptidase enzyme that hydrolyzes N-acetylaspartate to aspartate and acetate; ASPA gene mutations cause Canavan disease, a leukodystrophy targeted by AAV gene therapy.
Aspartylglucosaminidase
Aspartylglucosaminidase (AGA, glycosylasparaginase, EC 3.5.1.26) is a lysosomal Ntn-hydrolase on chromosome 4q34.3 that cleaves GlcNAc-Asn bonds; its deficiency causes aspartylglucosaminuria, common in Finland via the C163S founder mutation.
Aspartylglucosaminuria
Aspartylglucosaminuria (AGU, aspartylglucosaminidase deficiency) is a rare autosomal recessive lysosomal storage disorder from biallelic AGA variants on 4q34.3, enriched in Finland, causing developmental delay, neurodegeneration, and premature death; AAV9 gene therapy is in trials.
