| Outline of Final Research Achievements |
Egg ovalbumin has been applied as a model for polymerization or gelation of general food proteins. The mechanisms for polymerization or gelation of the protein have been elucidated by low resolution model with the images like string of beads. Though an atomic resolution model for oligomers of ovalbumin was asked in the present study, good crystal of initial oligomers has not been obtained after a number of trials of purification and preparation under various conditions. On the way of investigation, the authors found the importance of N-terminal segment of the protein on the polymerization process and some solvent-accessible serine residues might be crucial for the thermostability of the protein.
