Enzymatic Synthesis of Theanine in the Presence of L-glutaminase Produced by Trichoderma koningii

Applied Food Biotechnology, 2017
Background and Objective: Since ancient times, it has been said that drinking green tea brings relaxation. The substance that is responsible for a sense of relaxation is theanine. Theanine (γ-glutamylethylamide) is a unique non-protein amino acid. It gives an umami taste and a unique flavor to the tea, and has many physiological and pharmaceutical ...

Antioxidant potential of L-asparaginase and L-glutaminase excreted by Monascus sp.

OBSERVATÓRIO DE LA ECONOMÍA LATINOAMERICANA, 2023
The L-asparaginases and L-glutaminases can be excreted by various organisms such as bacteria and fungi, but also by animal and plant tissues. Studies indicate that these enzymes can be used in the food industry to improve the flavor of foods and in pharmaceuticals as an ally in the treatment of some types of cancer.

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

Animal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.

Characterization of structural features of food molten‐globule state proteins: An overview

Food Biomacromolecules, EarlyView.
Abstract During food processing, pH, ionic strength, and temperature drive conformational transitions from native states to partially folded intermediates and fully unfolded states. The molten‐globule (MG) state typically preserves substantial secondary structure but has relaxed tertiary packing, thereby modulating protein solubility, emulsifying ...

L‒asparaginase activity in some endophytic fungi: Glutaminase‒free and low urease co‒activities.

PLoS ONE
In this study, L‒asparaginase production in several endophytic fungi was evaluated along with their L‒glutaminase and urease co-activities. The effect of L‒asparagine and different culture media on L-asparaginase production were also evaluated. Among the
