抄録

In the marine red alga, Griffithsia pacifica, the repair process initiated upon death of an intercalary cell is mediated by a glycoprotein hormone, rhodomorphin. In this paper we show that the glycosidic portion of the molecule has terminal a-D-mannosyl residues which are at least in part responsible for the binding of rhodomorphin by concanavalin A. The protein portion of the molecule contains disulfide bridges. These bridges must be intact for biologically active hormone to be recovered from a denatured state. Isolation of active rhodomorphin from SDS-PAGE indicates a molecular weight of 15,000-17,500. This agrees well with our previously published [Watson and Waaland (1983) Plant Physiol. 71 : 327] molecular weight from gel filtration of 14,000.
