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.

The role of UDP‐glucose epimerase in carbohydrate metabolism of Arabidopsis [PDF]

The Plant Journal, 1998
SummaryUridine 5′‐diphospho‐glucose‐4‐epimerase (UDP‐Glc epimerase) catalyses the reversible epimerization of UDP‐galactose and UDP‐glucose. In contrast to bacteria and yeast, expression of the UDP‐Glc epimerase gene in Arabidopsis was found not to be induced by galactose.

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 ...

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

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 ...

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-

D-galactose catabolism in Penicillium chrysogenum: Expression analysis of the structural genes of the Leloir pathway [PDF]

, 2016
In this study, we analyzed the expression of the structural genes encoding the five enzymes comprising the Leloir pathway of D-galactose catabolism in the industrial cell factory Penicillium chrysogenum on various carbon sources.

Sn-Beta zeolites with borate salts catalyse the epimerization of carbohydrates via an intramolecular carbon shift [PDF]

, 2012
Carbohydrate epimerization is an essential technology for the widespread production of rare sugars. In contrast to other enzymes, most epimerases are only active on sugars substituted with phosphate or nucleotide groups, thus drastically restricting ...

Mannuronate C-5 epimerases and their use in alginate modification [PDF]

, 2023
Alginate is a polysaccharide consisting of β-D-mannuronate (M) and α-L-guluronate (G) produced by brown algae and some bacterial species. Alginate has a wide range of industrial and pharmaceutical applications, owing mainly to its gelling and ...

Characterization of the first bacterial and thermostable GDP-mannose 3,5-epimerase [PDF]

, 2019
GDP-mannose 3,5-epimerase (GM35E) catalyzes the conversion of GDP-mannose towards GDP-L-galactose and GDP-L-gulose. Although this reaction represents one of the few enzymatic routes towards the production of L-sugars and derivatives, it has not yet been ...
