The present disclosure discloses a method for modification of mung bean protein and preparation of simulated egg pulp based on the modified protein. A commercial mung bean protein isolate is used as a raw material in the present disclosure, then subjected to pH shift modification, ultrasonic treatment and protein-glutaminase treatment for compound modification to prepare a high-functionality modified mung bean protein isolate; and the modified mung bean protein isolate is used as a raw material, using high-speed emulsification and high-pressure homogenization are conducted to obtain a high-stability mung bean protein-based simulated egg pulp. In the present disclosure, the mung bean protein isolate prepared by compound modification has good solubility, emulsifying property and gelling property. The mung bean protein-based simulated egg pulp is in the form of a stable emulsion and has good fluidity and moderate gelling property, and uniformity and stability can still be maintained for a long time.

Method for making yogurt or another fermented milk-based product comprising the steps of: adding to the milk an enzyme preparation based on transglutaminase at a concentration of 0.5-3 units per gram of protein contained in the milk, the transglutaminase being supported on vegetable fibres; homogenising the milk by forcing it through a gap afforded between a lower annular chamber (9) and an upper annular chamber (10) of a homogenising valve (1).

Systems and methods for preparing plant-based cheese comprise preparing a plant-based cheese mixture, transferring the plant-based to a heat exchanger, heat treating* and cooling the plant-based mixture, dynamically mixing additional ingredients, possible homogenizing the plant-based cheese mixture, and packaging the homogenized plant-based cheese product. In embodiments, heat treatment can occur between 85-95° C. and cooling occurs at 65-70° C. Homogenization can occur before or after heat treatment. A related cheese making apparatus is also disclosed.

Site-specific modification of proteins with microbial transglutaminase (MTG) is a powerful and versatile strategy for a controlled modification of proteins under physiological conditions. Solid-phase microbead-immobilization is used to site-specifically and efficiently attach different functional molecules important for further downstream applications to proteins of therapeutic relevance including scFV, Fab-fragment and antibodies. MTG remained firmly immobilized with no detectable column bleeding and enzyme activity was sustained during continuous operation. Immobilized MTG shows enhanced selectivity towards a certain residue in the presence of several reactive residues which are all targeted when the conjugation was carried out in solution. The generation of dual site-specifically conjugated IgG1 with immobilized and MTG in solution is reported, i.e. site-specific conjugation to glutamine and lysine residues of IgG1 antibody. Site-specific glutamine conjugation with small peptides containing a lysine residue and a functional moiety is also described.

Engineered antibodies useful for site-specific conjugation by a transglutaminase are described. Also described are methods of site-specific conjugation of the antibodies, the site-specifically conjugated antibodies, and pharmaceutical compositions and uses related to the site-specifically conjugated antibodies.

The present invention relates to a method for producing an acidified milk product using an enzyme having transglutaminase activity.

The present disclosure provides antibody drug conjugates comprising STING modulators. Also provided are compositions comprising the antibody drug conjugates. The compounds and compositions are useful for stimulating an immune response in a subject in need thereof.

Sunscreen compositions and sunscreen active ingredients are disclosed herein which comprise at least one ketone-containing UV filter and at least one primary or secondary amine wherein at least one ketone-containing UV filter and at least one primary or secondary amine react to form an imine analog of the ketone-containing UV filter wherein the imine analog has at least one property selected from the group consisting of a) is capable of extending UV protection into a visible region equal to or greater than 400 nm, b) is water resistant, and/or c) prevents or decreases skin penetration. This imine analog may be further modified to provide a substrate capable of reacting with transglutaminase or any variant thereof and/or a lysyl oxidase to bind the sunscreen composition or sunscreen active ingredient to a target of interest. Also disclosed are cosmetic or pharmaceutical preparations comprising any of the sunscreen compositions or sunscreen ingredients along with a cosmetically or pharmaceutically acceptable carrier.
