Enzyme-loaded polymeric nanoparticles for the treatment of disorders such as neurological or non-neurological conditions are described. Using hydrophobic ion pairing, enzymes are loaded into polymeric nanoparticles while retaining enzymatic activity. Surfactants coating the nanoparticle can direct nanoparticles for cellular uptake or for aggregation in the extracellular matrix. Preparing a hydrophobic ion pairing complex for nanoparticle formation.

The present invention relates to isolated polypeptides having catalase activity and polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.

The present invention relates to methods of inhibiting AA9 lytic polysaccharide monooxygenase catalyzed inactivation of an enzyme composition or a component thereof, methods for increasing production of an enzyme composition, and methods for stabilizing an enzyme composition.

Disclosed are pharmaceutical compositions comprising a glucose oxidase enzyme and a peroxide-degrading enzyme (e.g., a catalase enzyme), which can be used, among other things, to treat hyperglycemia, diabetes, obesity, metabolic syndrome, and/or an eating disorder.

The present invention relates to processes for the formation of furandicarboxylic acid (FDCA), in particular 2,5-furandicarboxylic acid (2,5-FDCA), and mono- and diester derivatives thereof, via a multistep biocatalytic oxidation reaction of 5-hydroxymethylfurfural (HMF) using, for example, an enzyme selected from the group consisting of xanthine oxidoreductase (XOR), galactose oxidase variant M.sub.3-5, aldehyde dehydrogenase, and/or ketoreductase. The invention also relates to copolymers that comprise the furandicarboxylic acid monomers and derivatives thereof, processes for the formation of the copolymers and uses for the copolymers.

Methods of weight management for a subject are provided. Generally the methods comprising: administering an effective amount to the small intestine and/or large intestine of the subject of at least one agent that increases oxygen tension and/or redox potential and/or pH in the colon of the subject to thereby manage the weight of the subject. Also provided are compositions comprising at least one agent that increases oxygen tension and/or redox potential and/or pH, wherein the composition is formulated for delivery of an effective amount of the at least one agent to the small intestine and/or large intestine of a subject following oral ad ministration of the composition to the subject.

Enzyme compositions including lactate responsive enzyme and stabilizing agent, including electrodes, sensors, and systems having the same. The stabilizing agent stabilizes the lactate responsive enzyme in a manner sufficient to increase sensitivity to lactate, such as for use in in vivo detection of lactate. In some compositions the lactate responsive enzyme is lactate oxidase and the sensor includes a heterocycle-containing polymer and a crosslinker.

The present invention relates to methods for degrading or converting a cellulosic material, comprising: treating the cellulosic material with an enzyme composition in the presence of a polypeptide having catalase activity; and enzyme compositions used for degrading or converting a cellulosic material comprising one or more (e.g., several) enzymes having cellulolytic and/or hemicellulolytic activity and a polypeptide having catalase activity.

The present invention relates to the use of a secreted fungal catalase, for hydrogen-peroxide neutralization in growth media for the detection of microorganisms as well as to a method for detecting microorganisms in hydrogen peroxide-bearing aerosol or on a hydrogen peroxide bearing surface, said method comprising contacting said aerosol or surface with a growth medium comprising a secreted fungal catalase, and detecting growth of microorganisms in said medium.

The invention relates to methods, compositions and kits for determining the cleanness of a surface. Described herein is a kit for determining the cleanness of a surface comprising an enzymatic solution comprising catalase; and a developer solution comprising hydrogen peroxide. Described also is a method for determining the cleanness of a surface comprising: applying on a zone of a surface to be cleaned an enzymatic solution comprising catalase and letting it dry; after cleaning said surface, applying on said zone a developer solution comprising hydrogen peroxide; and detecting a catalytic reaction between remaining catalase and hydrogen peroxide, wherein presence of a catalytic reaction is indicative of a surface not properly cleaned. Also provided are specific enzymatic solutions and developer solutions for the kits and methods.
