Protoplasts derived from developing soybean cotyledons were used to study substrate recognition by a sucrose transporting protein in plant membranes. When used as alternate substrate inhibitors of [14C] sucrose influx, five different fructosyl-substituted sucrose derivatives, phenyl-alpha-D-glucopyranoside, and phenyl-alpha-D-thioglucopyranoside proved to bind effectively to the sucrose carrier-active site. These results are interpreted to indicate that a large portion of substrate recognition by this carrier may arise from the interaction of a relatively hydrophobic portion of the sucrose molecule and a hydrophobic region of the carrier protein binding site. Binding of phenyl-alpha-D-thioglucopyranosides in which various substitutions were made for the glucosyl hydroxyls shows that the glucosyl hydroxyls at positions 3, 4, and 6 are involved in substrate recognition by the carrier protein.
