Biophysical Characterization of Fibroblast Growth Factor Homologous Factor-1b (FHF-1b): Sodium Dodecyl Sulfate Promotes Two State Folding
Abstract:The current article describes the biophysical characterization and folding studies of fibroblast growth factor homologous factor-1b (FHF-1b) in comparison with acidic fibroblast growth factor (FGF-1). Our data indicates that FHF- 1 is significantly more stable than FGF-1. The folding mechanism of these two proteins seems to be different although they share high degree of sequence and structural similarity. FHF-1 unfolds through stable intermediate state while unfolding of FGF-1 is two-state. Interestingly, low concentration of sodium dodecyl sulfate (SDS) drives the folding pathway of FHF-1b to two-state.

- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
