Fig. 4. Partial cloning of the FBPase gene in rainbow trout. (A) Nucleotide and deduced amino acid sequences of the rainbow trout FBPase clone. Underlined letters correspond to the primer sequences. (B) Alignments of the partial amino acid deduced sequence from FBPase cDNA of the rainbow trout (T_FBPase) (GenBank accession number: AF333188) with mouse FBPase (M_FBPase) (GenBank accession number: AJ132693). Underlined letters correspond to the primer sequences. Asterisks mark amino acid residues homologous between FBPases. Conserved residues involved in the interaction with fructose-1,6-bisphosphate are marked by arrows (Ke et al., 1989).
