Fig. 1. Comparison of tomato fruit fructokinase with sugar beet (GenBank database U37838) and potato (11), S. typhimurium(1), K. pneumoniae(1) and V. algynolyticus (2) fructokinases. Deduced amino acid sequences were aligned using FeneWorks DNA analysis software (Molecular Dynamics). ATP binding (18,20) and substrate recognition (20) sequences as well as identical(*) and conserved(+) residues are marked. Gaps are represented by dashes.
