Beta-methylaspartase (EC 4.3.1.2) was purified 20-fold in 35% yield from Fusobacterium varium, an obligate anaerobe. The purification steps included heat treatment, fractional precipitation with ammonium sulfate and ethanol, gel filtration, and ion exchange chromatography on DEAE-Sepharose. The enzyme is dimeric

Glutamate mutase (GM) is a cobalamin-dependent enzyme that catalyzes the reversible interconversion of L-glutamate and L-threo-3-methylaspartate via a radical-based mechanism. To initiate catalysis, the 5'-deoxyadenosylcobalamin (AdoCbl) cofactor's Co-C bond is cleaved homolytically to generate an adenosyl radical and Co2+ Cbl.

We report the synthesis and biological activity of a series of side-chain-constrained RGD peptides containing the (2S,3R) or (2S,3S) beta-methyl aspartic acid within the RGD sequence. These compounds have been assayed for binding to the integrin receptors alpha(IIb)beta3 and alpha(v)beta3

Beta-(S-Methyl)thioaspartic acid occurs as a posttranslational modification at position 88 in Escherichia coli ribosomal protein S12, a position that is a mutational hotspot resulting in both antibiotic-resistant and antibiotic-sensitive phenotypes. Critical to research designed to determine the biological function of

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
