The purpose of the present invention is to provide a processing technology for increasing the free glutamic acid content of a protein hydrolysate. A processed plant protein-containing composition that is obtained by a method for producing a processed plant-containing composition which includes a step for treating a plant protein-containing composition with a proteolytic enzyme and a protein glutaminase has an increased free glutamic acid content.

The subject invention provides organoarsenicals or salts thereof, compositions comprising an organoarsenical or a salt thereof, and methods of using the organoarsenicals or salts thereof, or compositions for inhibiting glutaminase and for treating cancers. Specifically, the subject invention provides methods of inhibiting glutaminase (e.g., KGA) catalytic activity in a cell, methods of treating cancer or a tumor via, for example, the inhibition of glutaminase activity, and methods of disrupting and/or inhibiting growth and proliferation of cancerous or tumorous cells.

A method for preparing deamidated sweet whey protein powder via enzymatic deamidation; a whey protein beverage exhibiting high clarity and is essentially turbidity-free, and its method of preparation using the deamidated sweet whey protein powder.

Disclosed herein are methods of increasing nitrogen fixation in a non-leguminous plant. The methods can comprise exposing the plant to a plurality of bacteria. Each member of the plurality comprises one or more genetic variations introduced into one or more genes or non-coding polynucleotides of the bacteria's nitrogen fixation or assimilation genetic regulatory network, such that the bacteria are capable of fixing atmospheric nitrogen in the presence of exogenous nitrogen. The bacteria are not intergeneric microorganisms. Additionally, the bacteria, in planta, produce 1% or more of the fixed nitrogen in the plant.

The purpose of the present invention is to provide a processing technology that changes aroma of a plant protein-containing composition and/or enhances taste thereof. The aroma of the plant protein-containing composition can be changed and/or the taste thereof can be enhanced by treating the plant protein-containing composition with a protein deamidase.

The subject invention provides organoarsenicals or salts thereof, compositions comprising an organoarsenical or a salt thereof, and methods of using the organoarsenicals or salts thereof, or compositions for inhibiting glutaminase and for treating cancers. Specifically, the subject invention provides methods of inhibiting glutaminase (e.g., KGA) catalytic activity in a cell, methods of treating cancer or a tumor via, for example, the inhibition of glutaminase activity, and methods of disrupting and/or inhibiting growth and proliferation of cancerous or tumorous cells.

A method of producing plant protein extract, which comprises treating plant protein raw materials under alkaline conditions, recovering the protein and spray drying the recovered protein, wherein protein deamidase is added before alkaline treatment or during alkaline treatment or after alkaline treatment. The obtained plant protein extract has improved solubility which can be used in the food or beverage.
