In addition to ammonia, 3-methylaspartase is able to catalyse the conjugate addition of hydrazine, hydroxylamine, methoxylamine and alkylamines to various alkyl- and halogenofumaric acids to give single enantiomers of the corresponding N-substituted aspartic acids.

which revealed that AspB catalyzes all the additions with excellent enantioselectivity (>97 % ee). Its broad nucleophile specificity and high catalytic activity make AspB an attractive enzyme for the enantioselectivesynthesis of N-substituted asparticacids, which are interesting building blocks for peptide and pharmaceutical synthesis as well as for peptidomimetics.
