Exploiting catalytic promiscuity: The proline-based enzyme 4-oxalocrotonate tautomerase (4-OT) promiscuously catalyzes asymmetric Michael-type additions of linear aldehydes--ranging from acetaldehyde to octanal--to trans-β-nitrostyrene in aqueous solvent. The presence of 1.4 mol% of 4-OT effected formation of the anticipated γ-nitroaldehydes in fair
Bridging between organocatalysis and biocatalysis: asymmetric addition of acetaldehyde to β-nitrostyrenes catalyzed by a promiscuous proline-based tautomerase.

Serendipitous switch: While exploring cis-nitrostyrene as a potential electrophile in Michael-type addition reactions catalysed by the enzyme 4-oxalocrotonate tautomerase (4-OT), it was unexpectedly found that 4-OT catalyses the isomerisation of cis-nitrostyrene to trans-nitrostyrene (k(cat) /K(m) = 1.9×10(3)  M(-1)  s(-1) ).

Induction of apoptosis is perceived as the main intention of drug regimens for tumour therapy. Thus, the concentration- and time-dependence of drug-induced apoptosis should be carefully evaluated for experimental as well as for standard anti-tumour agents. A main feature of
