Disclosed herein are glucosyltransferases with modified amino acid sequences. Such engineered enzymes exhibit improved alpha-glucan product yields and/or lower leucrose yields, for example. Further disclosed are reactions and methods in which engineered glucosyltransferases are used to produce alpha-glucan.

Engineered glucosyltransferases

An oral care composition including a hydrophobic phase and a hydrophilic phase is disclosed. The hydrophobic phase may include a source of hydrogen peroxide and an acyl donor, and the hydrophilic phase may include an enzyme having perhydrolytic activity that catalyzes the generation of peracetic acid between the source of hydrogen peroxide and the acyl donor.

Oral care compositions and methods for increasing the stability of the same

Compositions are disclosed herein comprising dextran that comprises (i) 87-93 wt % glucose linked at positions 1 and 6; (ii) 0.1-1.2 wt % glucose linked at positions 1 and 3; (iii) 0.1-0.7 wt % glucose linked at positions 1 and 4; (iv) 7.7-8.6 wt % glucose linked at positions 1, 3 and 6; and (v) about 0.4-1.7 wt % glucose linked at (a) positions 1, 2 and 6, or (b) positions 1, 4 and 6. Aqueous forms of this composition have enhanced viscosity profiles. Further disclosed are methods of using compositions comprising dextran, such as increasing the viscosity of an aqueous composition. Enzymatic reactions for producing dextran are also disclosed.

Enzymatically polymerized gelling dextrans

An enzymatically produced soluble α-glucan fiber composition is provided suitable for use as a digestion resistant fiber in food and feed applications. The soluble α-glucan fiber composition can be blended with one or more additional food ingredients to produce fiber-containing compositions. Methods for the production and use of compositions comprising the soluble α-glucan fiber are also provided.

Enzymatic synthesis of soluble glucan fiber

Described herein are oral care compositions, comprising a peroxydone complex, a dispersant, and a polyvinylpyrrolidone copolymer structure-building agent.

Oral care compositions

Disclosed herein are proteins capable of forming glucans having alpha-1,2 linkages/branches, reactions and methods for producing such glucan, compositions comprising such glucan, and various applications thereof.

Polypeptides capable of producing glucans having alpha (1-->2) linkages and use of the same

An enzymatically produced α-glucan oligomer/polymer compositions is provided. The enzymatically produced α-glucan oligomer/polymers can be derivatized into α-glucan ether compounds. The α-glucan oligomers/polymers and the corresponding α-glucan ethers are cellulose and/or protease resistant, making them suitable for use in fabric care and laundry care applications. Methods for the production and use of the present compositions are also provided.

Glucan fiber compositions for use in laundry care and fabric care

An oral care composition, including a catalyzing enzyme and an anhydrous matrix configured to at least partially stabilize the catalyzing enzyme, wherein the anhydrous matrix includes a source of hydrogen peroxide, an acyl donor, a non-aqueous anhydrous liquid, and a surfactant mixture including sodium lauryl sulfate (SLS), Betaine, and a poloxamer.

An oral care kit comprising an oral care implement having a first reservoir containing a first oral care agent comprising a first whitening reagent that includes triacetin; and a container having a second reservoir containing a second oral care agent, the second oral care agent comprising a catalytic enzyme and a second whitening reagent that includes peroxide forming compound.

Whitening system

An enzymatically produced &#x3b1;-glucan oligomer/polymer compositions is provided. The enzymatically produced &#x3b1;-glucan oligomer/polymers can be derivatized into &#x3b1;-glucan ether compounds. The &#x3b1;-glucan oligomers/polymers and the corresponding &#x3b1;-glucan ethers are cellulose and/or protease resistant, making them suitable for use in fabric care and laundry care applications. Methods for the production and use of the present compositions are also provided.

A two-phase oral care whitening composition including a hydrophobic phase and a hydrophilic phase, and methods for oral care whitening teeth with the same are provided. The hydrophobic phase may include a source of hydrogen peroxide and an acyl donor. The hydrophilic phase may include an enzyme that catalyzes the generation of peracetic acid between the source of hydrogen peroxide and the acyl donor. At least one of the hydrophobic phase and the hydrophilic phase may further include at least one surfactant.
