概要
In macerates of black cherry (Prunus serotina Ehrh.) leaves and stems, (R)-prunasin is catabolized to HCN, benzaldehyde, and D-glucose by the sequential action of prunasin hydrolase (EC 3.2.1.21) and (R)-(+)-mandelonitrile lyase (EC 4.1.2.10). Immuno-cytochemical techniques have shown that within these organs prunasin hydrolase occurs within the vacuoles of phloem parenchyma cells. In arborescent leaves, mandelonitrile lyase was also located in phloem parenchyma vacuoles, but comparison of serial sections revealed that these two degradative enzymes are usually localized within different cells.
