evolutionary appearance of non‐cyanogenic hydroxynitrile glucosides in the Lotus genus is accompanied by the substrate specialization of paralogous β–glucosidases resulting from a crucial amino acid substitution

Lotus japonicus, like several other legumes, biosynthesizes the cyanogenic α–hydroxynitrile glucosides lotaustralin and linamarin. Upon tissue disruption these compounds are hydrolysed by a specific β–glucosidase, resulting in the release of hydrogen cyanide. Lotus japonicus also produces the non‐cy...
