A nitrilase gene from Alcaligenes sp. ECU0401 was cloned and overexpressed in Escherichia coli BL21 (DE3) in a soluble form. The encoded protein with a His₆-tag was purified to nearly homogeneity as revealed by SDS-PAGE with a molecular weight of

A hydroxynitrile lyase from the passion fruit Passiflora edulis (PeHNL) was isolated from the leaves and showed high stability in biphasic co-organic solvent systems for cyanohydrin synthesis. Cyanohydrins are important building blocks for the production of fine chemicals and pharmaceuticals.

A nitrilase-mediated pathway has significant advantages in the production of optically pure (R)-(-)-mandelic acid. However, unwanted byproduct, low enantioselectivity, and specific activity reduce its value in practical applications. An ideal nitrilase that can efficiently hydrolyze mandelonitrile to optically pure (R)-(-)-mandelic

Mining sequence data is increasingly important for biocatalysis research. However, when relying on sequence data alone, prediction of the reaction catalyzed by a specific protein sequence is often elusive, and substrate specificity is far from trivial. The present study demonstrated
Laboratory evolved biocatalysts for stereoselective syntheses of substituted benzaldehyde cyanohydrins.
