The nitrilases from Fusarium solani O1 and Aspergillus niger K10 showed a broad substrate specificity for carbocyclic and nonaromatic heterocyclic amino nitriles, the preferred substrates being five-membered g-amino nitrile , six-membered g-amino nitriles , and , pyrrolidine-3-carbonitriles and as well as piperidine-4-carbonitriles 14a and 15a. Both enzymes showed a strong diastereopreference for cis- vs. trans-g-amino nitriles. The electronic and steric effects of N-protecting groups affected the reactivity of the nitriles. Amides as by-products of the nitrilase-catalyzed reaction were produced from heterocyclic amino nitriles, 14a and 15a by the A. niger enzyme but only from nitrile by the F. solani enzyme.
