 Title    Separation of 13-and 9-Hydroperoxide Lyase Activities in Cotyledons of Cucumber Seedlings  
 Abstract    In cucumber cotyledons, both C6-and C9-aldehyde were formed via hydroperoxide (H PO) lyase activity. Because it has not been elucidated whether these activities are attri­ buted to one enzym e which can cleave both 13-and 9-H PO or to two or more enzym es each o f which specifically cleaves 13-or 9-H PO , an attempt to separate HPO lyase activity was done. Ion exchange chromatography separated this activity into two fractions, one o f which specifically cleaved 13-hydroperoxylinoleic acid and the other specifi­ cally cleaved the 9-isomer. 13-H PO -specific activity was most active at pH 8.0 and 9-H PO -specific one was at pH 6.5. SH -reagents inhibited both the lyases but to differ­ ent extents.
