Repression Effects of Hydrolysates from Hen-Egg Proteins on Amyloid Fibril Formation.

Amyloid fibrils, which are formed from aggregates of aberrant proteins, can cause various forms of amyloidosis (including Alzheimer's disease). Such disorders often occur in elderly populations and are suspected to be lifestyle related. Thus, it has been speculated that some foodstuffs could be beneficial for preventing amyloidosis.

Cloning and overexpression of Bacillus cereus penicillin-binding protein 3 gene in Escherichia coli.

The pbp3 gene encoding PBP3 of Bacillus cereus was cloned and sequenced. For this purpose, PBP3 was first purified from B. cereus ts-4, and N-terminal amino acid sequences of the peptides obtained from the protease digests of the protein were analyzed.
