Carbohydrate utilization in Streptococcus thermophilus: characterization of the genes for aldose 1-epimerase (mutarotase) and UDPglucose 4-epimerase [PDF]

Journal of Bacteriology, 1990
The complete nucleotide sequences of the genes encoding aldose 1-epimerase (mutarotase) (galM) and UDPglucose 4-epimerase (galE) and flanking regions of Streptococcus thermophilus have been determined. Both genes are located immediately upstream of the S. thermophilus lac operon.

RmlC, a C3′ and C5′ Carbohydrate Epimerase, Appears to Operate via an Intermediate with an Unusual Twist Boat Conformation [PDF]

Journal of Molecular Biology, 2007
The striking feature of carbohydrates is their constitutional, conformational and configurational diversity. Biology has harnessed this diversity and manipulates carbohydrate residues in a variety of ways, one of which is epimerization. RmlC catalyzes the epimerization of the C3' and C5' positions of dTDP-6-deoxy-D-xylo-4-hexulose, forming dTDP-6-deoxy-

Functional Characterization of the Rice UDP-glucose 4-epimerase 1, OsUGE1: A Potential Role in Cell Wall Carbohydrate Partitioning during Limiting Nitrogen Conditions

PLoS ONE, 2014
Plants grown under inadequate mineralized nitrogen (N) levels undergo N and carbon (C) metabolic re-programming which leads to significant changes in both soluble and insoluble carbohydrate profiles. However, relatively little information is available on the genetic factors controlling carbohydrate partitioning during adaptation to N-limitation ...

Metabolic mechanism of mannan in a ruminal bacterium, Ruminococcus albus, involving two mannoside phosphorylases and cellobiose 2-epimerase: discovery of a new carbohydrate phosphorylase, β-1,4-mannooligosaccharide phosphorylase.

The Journal of biological chemistry, 2013
Ruminococcus albus is a typical ruminal bacterium digesting cellulose and hemicellulose. Cellobiose 2-epimerase (CE; EC 5.1.3.11), which converts cellobiose to 4-O-β-D-glucosyl-D-mannose, is a particularly unique enzyme in R. albus, but its physiological function is unclear.

Osmolality‐Independent Impact of Sodium on Glycosylation of an Fc‐Fusion Protein and the Hexosamine Biosynthesis Pathway in a Chinese Hamster Ovary Cell Line

Biotechnology Journal, Volume 21, Issue 6, June 2026.
Graphical Abstract and Lay Summary Sodium and potassium supplementation in CHO batch culture elevates intracellular UDP‐HexNAc concentrations through activation of the hexosamine biosynthesis pathway (HBP), independently of osmolality. Increased nucleotide sugar availability enhances Fc‐fusion protein glycosylation and reduces the abundance of low ...

Glucose-6-Phosphate 1-Epimerase Responds to Phosphate Starvation by Regulating Carbohydrate Homeostasis in Rice and Arabidopsis

Plants
Plants adapt to phosphate starvation by remodeling root architecture and reallocating carbohydrates. Glucose-6-phosphate 1-epimerase (G6PE), a key enzyme in carbon and energy metabolism, is hypothesized to contribute to phosphate starvation responses. Here, we investigated the role of G6PE in rice and Arabidopsis through phenotypic, physiological, and ...

Deciphering the soybean root rot pathogen Phytophthora sojae: Signaling pathways, transcriptional regulation, and effector biology

New Plant Protection, Volume 3, Issue 2, June 2026.
This review highlights how Phytophthora sojae utilizes unconventional lineage‐specific signaling networks, including unique G protein‐coupled receptor fusions, expanded kinases, and rapidly evolving effectors, to infect soybeans. Understanding these divergent molecular paradigms reveals critical vulnerabilities in this destructive pathogen, offering ...

Computational insights into carbohydrate epimerase mechanisms

, 2023
[eng] Carbohydrates, as the most abundant biomolecules, play a myriad of roles and functions in biological systems. Unlike the building blocks of proteins, amino acids, whose chemical structure can vary significantly, monosaccharides, the building blocks of carbohydrates, can exhibit small differences in their chemical structure that lead to a very ...
