His-65 in the proton–sucrose symporter is an essential amino acid whose modification with site-directed mutagenesis increases transport activity
The proton–sucrose symporter that mediates phloem loading is a key component of assimilate partitioning in many higher plants. Previous biochemical investigations showed that a diethyl pyrocarbonate-sensitive histidine residue is at or near the substrate-binding site of the symporter. Among the prot...
