Representing catalytic mechanisms with rule composition [PDF]
Reaction mechanisms are often presented as sequences of elementary steps, such as codified by arrow pushing. We propose an approach for representing such mechanisms using graph transformation. In this framework, each elementary step is a rule for modifying a molecular graph and a mechanism is a sequence of such rules.

Uncovering the molecular mechanisms of lignocellulose digestion in shipworms [PDF]
Lignocellulose forms the structural framework of woody plant biomass and represents the most abundant carbon source in the biosphere. Turnover of woody biomass is a critical component of the global carbon cycle, and the enzymes involved are of increasing

A new group of glycoside hydrolase family 13 α-amylases with an aberrant catalytic triad
α-Amylases are glycoside hydrolase enzymes that act on the α(1→4) glycosidic linkages in glycogen, starch, and related α-glucans, and are ubiquitously present in Nature. Most α-amylases have been classified in glycoside hydrolase family 13 with a typical

Key Regulators of Parasite Biology Viewed Through a Post‐Translational Modification Repertoire
ABSTRACT Parasites are the leading causes of morbidity and mortality in both humans and animals, imposing substantial socioeconomic burdens worldwide. Controlling parasitic diseases has become one of the key issues in achieving “One Health”. Most parasites have sophisticated life cycles exhibiting progressive developmental stages, morphologies, and ...

The structure of a family 168 glycoside hydrolase from the marine bacterium Muricauda eckloniae
The structure of a putative fucoidan‐degrading glycoside hydrolase assigned to glycoside hydrolase family 168 reveals a (β/α)8 fold. The catalytic machinery and potential substrate specificity were investigated through a structural comparison with a Fun168A oligosaccharide complex.The genome of the marine bacterium Muricauda eckloniae sp.

RNA sampling and crystallographic refinement using Rappertk [PDF]
Background. Dramatic increases in RNA structural data have made it possible to recognize its conformational preferences much better than a decade ago. This has created an opportunity to use discrete restraint-based conformational sampling for modelling RNA and automating its crystallographic refinement. Results.

Characterization of thermophilic β-Glucosidase of rhizospheric bacterial strain (LSKB15) isolated from Cholistan Desert, Pakistan [PDF]
Fifty thermophilic bacterial strains isolated from rhizospheric soil of Cholistan desert, Pakistan, and designated as LSKB01-LSKB50 were screened for β-glucosidase gene (bgl) belonging to glycoside hydrolase family 1 (GH 1) using PCR technique ...
