Disaccharide phosphorylases: Structure, catalytic mechanisms and directed evolution
Disaccharide phosphorylases (DSPs) are carbohydrate-active enzymes with outstanding potential for the biocatalytic conversion of common table sugar into products with attractive properties. They are modular enzymes that form active homo-oligomers. From a

Evolution of Phosphorylases from N-Acetylglucosaminide Hydrolases in Family GH3
Glycoside phosphorylases hold great potential as catalysts for the synthesis of valuable sugars, glycosides, and glycans or for the development of energy-efficient microbial cell factories.

Co-receptor CD8-mediated modulation of T-cell receptor functional sensitivity and epitope recognition degeneracy [PDF]
The interaction between T-cell receptors (TCRs) and peptide epitopes is highly degenerate: a TCR is capable of interacting productively with a wide range of different peptide ligands, involving not only cross-reactivity proper (similar epitopes elicit ...

Old player, new roles: defining the role of the plastidial phosphorylase. [PDF]
Summary The plastidial phosphorylase (Pho1 or Phs1; E.C. 2.4.1.1) is a ubiquitous enzyme among plants that catalyzes the formation and degradation of glucans. Although the first report connecting Pho1 with starch metabolism came out > 80 years ago, its precise role is still a matter of debate.

Glycoside hydrolases and phosphorylases are two major classes of enzymes responsible for the cleavage of glycosidic bonds. Here we show that two GH84 O-GlcNAcase enzymes can be converted to efficient phosphorylases by a single point mutation. Noteworthy,

Structural and catalytic analysis of two diverse uridine phosphorylases in Phytophthora capsici
Uridine phosphorylase (UP) is a key enzyme of pyrimidine salvage pathways that enables the recycling of endogenous or exogenous-supplied pyrimidines and plays an important intracellular metabolic role.

Structure of purine nucleoside phosphorylase (DeoD) from Bacillus anthracis [PDF]
Protein structures from the causative agent of anthrax (Bacillus anthracis) are being determined as part of a structural genomics programme. Amongst initial candidates for crystallographic analysis are enzymes involved in nucleotide biosynthesis, since ...

Thermodynamic reaction control of nucleoside phosphorolysis [PDF]
Nucleoside analogs represent a class of important drugs for cancer and antiviral treatments. Nucleoside phosphorylases (NPases) catalyze the phosphorolysis of nucleosides and are widely employed for the synthesis of pentose‐1‐phosphates and nucleoside ...
