Protein
Sucrose transport protein SUC1
Organism
Arabidopsis thaliana
Function
Responsible for the transport of sucrose into the cell, with the concomitant uptake of protons (symport system). This transport is both voltage- and energy-dependent. Can also transport other glucosides such as maltose, alpha-phenylglucoside and beta-phenylglucoside. May also transport biotin. Required for normal pollen germination and anthocyanin accumulation induced by sucrose.
Similarity
Belongs to the glycoside-pentoside-hexuronide (GPH) cation symporter transporter (TC 2.A.2.4) family.
