UniProt Comments
Responsible in a heterologous system for the transport of sucrose into the cell, with the concomitant uptake of protons (symport system). Can also transport biotin, and probably maltose at a lesser rate. In planta, the role of SUC5 for the transport of sucrose seems to be negligible. Plays a role in the nutrition of the filial tissues during early seed development and is probably involved in the import of biotin into the endosperm and the embryo epidermis.
