a DNase sold under the trade name Pulmozyme by Genentech Tissue plasminogen activator (TPA) Activase by Genentech Glucocerebrosidase: Ceredase by Genzyme Interferon (IF) Interferon-beta-1a: Avonex from Biogen Idec; Rebif from Serono; Interferon beta-1b as Betaseron from Schering. It is being investigated for the treatments of diseases including Guillain-Barré syndrome and multiple sclerosis. Insulin-like growth factor 1 (IGF-1) Rasburicase, a Urate Oxidase analog sold as Elitek from Sanofi Animal recombinants Medicinal applications Bovine somatotropin (bST) Porcine somatotropin (pST) Bovine Chymosin Bacterial recombinants Industrial applications Xylanases Proteases, which have found applications in both the industrial (such as the food industry) and domestic settings. Viral recombinants Medicinal applications Envelope protein of the hepatitis B virus marketed as Engerix-B by SmithKline Beecham HPV Vaccine proteins Plant recombinants Research applications Polyphenol oxidases (PPOs): These include both catechol oxidases and tyrosinases. In additional to research, PPOs have also found applications as biocatalysts. Cystatins are proteins that inhibit cysteine proteases. Research are ongoing to evaluate the potential of using cystatins in crop protection to control herbivorous pests and pathogens. Industrial applications Laccases have found a wide range of application, from food additive and beverage processing to biomedical diagnosis, and as cross‐linking agents for furniture construction or in the production of biofuels. The tyrosinase‐induced polymerization of peptides offers facile access to artificial mussel foot protein analogues. Next generation universal glues can be envisioned that perform effectively even under rigorous seawater conditions and adapt to a broad range of difficult surfaces.
