Abstract
Synthetic peptides have found increasing use in dissecting cell signalling pathways and have been employed as synthetic antigens, protein kinase and protease substrates. Recently, it has become evident that relatively short (10–30mer) peptides are able to mimic that part of the signalling protein to which their sequence corresponds. In particular, peptides corresponding to the C-terminus of Zea mays auxin binding protein, ZmABPl, were able to modulate ion channel function within Vicia guard cells. In this report, GTPγS binding to NaCl-washed Zea microsomal membranes is shown to be stimulated by peptide A6.2, corresponding to the C-terminal 16 residues of ZmABPl, only when the membranes are reconstituted with soluble Zea protein fractions containing GPal and Gao homologues.
