Aspartates 25 and 125, the active site residues of HIV-1 protease, participate functionally in proteolysis by what is believed to be a general acid-general base mechanism. However, the structural role that these residues may play in the formation and maintenance

The enzyme 3-methylaspartate ammonia-lyase (EC 4.3.1.2) catalyzes the exchange of the C-3 hydrogen of the substrate, (2S,3S)-3-methylaspartic acid, with solvent hydrogen. The mechanism of the exchange reaction was probed using (2S,3S)-3-methylaspartic acid and its C-3-deuteriated isotopomer. Incubations conducted in tritiated

beta-methyl-aspartic acid is a substrate for beef kidney D-aspartate oxidase. The first product of a typical oxidative deamination, undergoes further spontaneous process of decarboxylation which gives as product, the alpha-keto-butyric acid.

Methylaspartate ammonia-lyase (3-methylaspartase, MAL; EC ) catalyzes the reversible anti elimination of ammonia from L-threo-(2S,3S)-3-methylaspartic acid to give mesaconic acid. This reaction lies on the main catabolic pathway for glutamate in Clostridium tetanomorphum. MAL requires monovalent and divalent cation cofactors
