Designed metalloenzymes made by modifying a native protein scaffold have shown unusually high levels of efficiency and longevity and have revealed new details about the way oxidases, the natural enzymes they mimic, may work. The study is an important step in efforts to design customized enzymes for a variety of potential biological and alternative-energy applications. Full article here.

The Natural Health Products Directorate (NHPD) will be seeking your feedback on proposed revisions to the enzyme abbreviated labelling standards (AbLS). In September 2011, NHPD published 12 AbLS for enzyme ingredients outlining the minimum documentation requirements and specifications for products containing these enzymes. Since posting the new AbLS, NHPD has been consulting with stakeholders regarding the requirements for products containing enzymes. As a result of these consultations, NHPD has revised the 12 AbLS for enzymes and developed a new Multi-Ingredient Enzyme AbLS. These will be published for a 30-day consultation period. Consultation starts from the time the documents are officially posted on the Health Canada website. Proposed Revised and New Enzyme Abbreviated [...]
