Chalcone isomerase isozymes with different substrate specificities towards 6'-hydroxy- and 6'-deoxychalcones in cultured cells of Glycyrrhiza echinata, a leguminous plant producing 5-deoxyflavonoids.
Three chalcone isomerase isozymes in Glycyrrhiza echinata (Fabaceae) were separated by chromatofocusing and partially purified to examine their substrate specificities. Two isozymes, one of which was elicitor-inducible, acted on both 6'-hydroxychalcone and 6'-deoxychalcone and presumably are involved in the legume-specific 5-deoxyflavonoid pathway, while another acted on only 6'-hydroxychalcone.
