- Archae are the source of many enzymes used for biocatalysis in diverse industries such as food and feed, pharmaceuticals, detergent, and beverage industries. These enzymes have unique structural and functional properties that enable use under extreme conditions.

Based on these characteristics, where are they typically found? The functional properties are linked to protein structural characteristics that imparts unique functional properties. For alkaliphiles and thermophiles, what structural elements (or characteristics) within the enzyme structure create these unique properties? See Table 2. Briefly discuss how the unique properties of these enzymes may be beneficial to the design of bioseparation processes. To recover intracellular enzymes, the Archae need to be lysed.
