A schematic diagram illustrating the functional domains of SlSBPase and multiple alignments of SlSBPase-related proteins.
(a) SDS-PAGE of SlSBPase protein. Arrows indicate the HIS-SlSBPase protein. (b) Structure of SlSBPase. (c) Alignment of deduced amino acid sequences of SBPase from five plant species. Identical amino acid residues are shown on grey backgrounds. The amino acid residues showing the regions involved in redox-regulated activation of SBPase are boxed. F1–F6 amino acid residues are six SBPase fingerprints. The accession numbers of SBPase in GenBank are as follows: Solanum lycopersicum, FJ959073; Arabidopsis thaliana, AEE79443; Cucumis sativus, ACQ82818; Oryza sativa, AAO22558; Triticum aestivum, CAA46507.
