The code history. Traditional wired glass (non-safety) is not banned. It can still be used in fire windows in non-hazardous locations, but is limited to 25 percent of the wall area. This size limitation applies to all fire protective glazing.raditional wired glass (non-safety) is not banned. Confusion in the marketplace continues to surround wired glass due in part to its code history. In 1977, the CPSC developed 16 CFR 1201 to protect people from injuries due to accidental impact with glazing in certain locations.
Nattokinase is an alkaline serine protease with an amino acid sequence similar to subtilisin, which is used in laundry detergents. The enzyme catalyses the cleavage of protein to polypeptides. It can withstand temperatures of up to 50Â°C and repeated freezing and thawing, but is inactive in acidic conditions.
Nattokinase (pronounced nat-oh-KY-nase) is an enzyme (EC 3.4.21.62) extracted and purified from a Japanese food called nattÅ. NattÅ is made from fermented soybeans and has been eaten in Japan for about a thousand years. NattÅ is produced by fermentation by adding the bacterium Bacillus natto to boiled soybeans. Nattokinase is produced by the bacterium acting on the soybeans. While other soy foods contain enzymes, it is only the nattÅ preparation that contains the specific nattokinase enzyme. In spite of its name, nattokinase is not a kinase enzyme, but a serine protease of the subtilisin family. It exhibits a strong fibrinolytic activity. Nattokinase can now be produced by recombinant means and in batch culture, rather than relying on extraction from NattÅ.
