Abstract

The specificity of two separate tonoplast permeases transporting oleanolic acid glycosides was investigated in vacuoles isolated from leaf protoplasts of marigold (Calendula officinalis) with the use of chemically synthesized analogs. The results indicate that the proper structure of both parts of oleanolic acid monoglycoside, i.e. aglycon and the sugar moiety, are required for binding to a specific tonoplast carrier.
