Summary: | This study identifies new acyl donors for manufacturing statin analogues through the acylation of monacolin J acid by the laboratory evolved acyltransferase LovD9. Vinyl and p‐nitrophenyl esters have emerged as alternate substrates for LovD9‐catalyzed acylation. While vinyl esters can reach product yields as high as the ones obtained by α‐dimethyl butyryl‐S‐methyl‐3‐mercaptopropionate (DMB‐SMMP), the thioester for which LovD9 was evolved, p‐nitrophenyl esters display a reactivity even higher than DMB‐SMMP for the first acylation step yet the acylation product yield is lower. The reaction mechanisms were elucidated through quantum mechanics (QM) calculations.
This study unveils the substrate promiscuity of acyltransferase LovD9, which turns to be very efficient by accepting vinyl and p‐nitrophenyl derivatives as acyl donors for the obtaining of statin analogues. |
