Self‐assembling protein scaffold‐mediated enzymes' immobilization enhances in vitro d‐tagatose production from lactose

Food Bioengineering, 2022
As a rare low‐calorie sugar with special medicinal value, d‐tagatose is widely used in the field of food, beverages, medicine, and cosmetics. However, enzymatic d‐tagatose production in vitro is commonly limited to low conversion efficiency and poor ...

Purification and Properties of an L-Arabinose Isomerase from Escherichia coli

Journal of Biological Chemistry, 1968
Abstract An l-arabinose isomerase has been purified 12-fold from l-arabinose-induced cultures of Escherichia coli B/r strain F' araB-24/araB-24. The enzyme is homogeneous in the ultracentrifuge and better than 98% pure by disc acrylamide electrophoresis. The s020,w is 12.65 x 10-13 sec at pH 7.6, 12.72 x 10-13 sec at pH 6.0, and 12.66 x 10-13 sec at pH

Extending the Farquhar–von Caemmerer–Berry photosynthesis model to account for various photorespiratory bypasses

New Phytologist, EarlyView.
We extend a widely used C3‐photosynthesis model to account for various photorespiratory bypasses, thereby, providing a useful resource and framework that enforces future novel bypass work and scrutinize if the results go counter to theory. Our model analyses show that of the 17 published bypass pathways, full‐decarboxylating bypasses (that have been ...

The Mycobacterium tuberculosis Rv0132c Gene Product Mtb‐FGD2 Can Act as an F420‐Dependent Glucose Dehydrogenase

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 9, Page 1610-1627, September 2026.
ABSTRACT The role of the cell envelope‐associated Rv0132c/FGD2 from Mycobacterium tuberculosis has long been a subject of debate. Importantly, FGD2 is found only in pathogenic mycobacteria, making it a potential drug target. While some suggest it functions as a glucose‐6‐phosphate dehydrogenase, others propose it acts instead as an F420‐dependent ...

Mind the Porins: Differential Effects of Porin Knockouts and Overexpression on Glucose and Xylose Uptake and Utilization in Pseudomonas putida

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
Altering the levels of outer membrane (OM) porins has an effect on the dynamics of the utilization and co‐utilization of native (glucose—green hexagon) and non‐native (xylose—brown pentagon) sugars, as well as the accumulation of their oxidation byproducts in Pseudomonas putida cultures.

The shape of L-arabinose isomerase from Escherichia coli.

Journal of Biological Chemistry, 1978
L-Arabinose isomerase, EC 5.3.1.4, catalyzes the conversion of L-arabinose to L-ribulose, the first step in the catabolism of L-arabinose by Escherichia coli B/r. Patrick and Lee (1969) J. Biol. Chem. 244, 4277--4283) demonstrated that native L-arabinose isomerase is composed of six identical subunits of approximately Mr = 60,000.

Tetrastigma Hemsleyanum Polysaccharide Suppresses Triple‐Negative Breast Cancer by Disrupting the Hippo‐YAP/TEAD4‐PDIA4 Axis and Endoplasmic Reticulum Stress Adaptation

Advanced Science, Volume 13, Issue 34, 19 June 2026.
ABSTRACT Triple‐negative breast cancer (TNBC) exhibits addiction to chronic endoplasmic reticulum (ER) stress, which sustains an aggressive metastatic phenotype through activation of the unfolded protein response (UPR). Here, we identify a previously unrecognized “ER‐stress addiction” axis in which the Hippo pathway effector TEAD4 directly ...

Bioconversion of carotenoids into high‐value crocins using a marine sponge carotenoid cleavage dioxygenase

New Phytologist, Volume 250, Issue 5, Page 3230-3246, June 2026.
Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites
