GCN2 adapts protein synthesis to scavenging-dependent growth

Hsin-Jung Li

Pancreatic cancer cells with limited access to free amino acids can grow by scavenging extracellular protein. In a murine model of pancreatic cancer, we performed a genome-wide CRISPR screen for genes required for scavenging-dependent growth. The screen id ...

How General Is Anomeric Retention during Collision-Induced Dissociation of Glycans?

Thomas Rizzo, Ahmed Ben Faleh, Stephan Warnke, Eduardo Carrascosa Casado, Robert Paul Pellegrinelli, Lei Yue

: Despite the essential role that glycans play in many biological processes, their isomeric com-plexity makes their structural determination partic-ularly challenging. Tandem mass spectrometry has played a central role in glycan analysis, and recent work h ...

Structure and Function of the T4 Spackle Protein Gp61.3

Petr Leiman

The bacteriophage T4 genome contains two genes that code for proteins with lysozyme activity-e and 5. Gene e encodes the well-known T4 lysozyme (commonly called T4L) that functions to break the peptidoglycan layer late in the infection cycle, which is requ ...

Structural studies suggest a peptidoglycan hydrolase function for the Mycobacterium tuberculosis Tat-secreted protein Rv2525c

Stewart Cole, Raju Mukherjee, Sophie Magnet

Among the few proteins shown to be secreted by the Tat system in Mycobacterium tuberculosis, Rv2525c is of particular interest, since its gene is conserved in the minimal genome of Mycobacterium leprae. Previous evidence linked this protein to cell wall me ...

Wagging the Tail: Essential Role of Substrate Flexibility in FAAH Catalysis

Ursula Röthlisberger, Marilisa Neri, Pablo Campomanes Ramos, Giulia Palermo, Andrea Cavalli

The serine hydrolase, fatty acid amide hydrolase (FAAH), is responsible for the intracellular degradation of anandamide and other bioactive fatty acid ethanolamides involved in the regulation of pain, inflammation, and other pathophysiological processes. T ...

Synthesis of Glycomimetics as Potential Anti-Cancer Agents

Annabelle Gillig

Cancer cells exhibit different properties that make them dangerous to the host, such as the ability to invade other tissues and the abnormal response to the control mechanisms that regulate the division of normal cells, which allow them to divide in a rela ...

Design and synthesis of acetamido tri- and tetra-hydroxyazepanes: Potent and selective beta-N-acetylhexosaminidase inhibitors

Pierre Vogel

A series of seven-membered iminosugars bearing an acetamido group beta- or gamma- to the endocyclic nitrogen have been synthesized via simple transformations of previously described polysubstituted azepanes. These tetra- and trihydroxylated acetamido azepa ...

Parameter and process significance in mechanistic modeling of cellulose hydrolysis

David Andrew Barry

A process-based model relevant to landfill and anaerobic digesters was developed, which included a novel approach to biomass transfer between a cellulose-bound biofilm and biomass in the bulk liquid. Model results highlighted the significance of the bacter ...

Development of new anticancer agents based on [alpha]-mannosidase inhibition

Hélène Fiaux

Enzymes that are involved in the synthesis and processing of oligosaccharides, such as glycosidases, are important catalysts for the specific assembly of oligosaccharide structures on proteins. Design and preparation of selective inhibitors of these enzyme ...

Synthesis of aza-C-disaccharides

Eliazar Rodriguez Garcia

Cell surface oligosaccharides control cell adhesion, fertilization, inflammation, the immune response and metastasis. Their biosynthesis implies sequences of reactions catalysed by glycosidases and glycosyltranferases. Inhibitors of these enzymes are there ...

A Chemoenzymatic Approach for the Synthesis of Unnatural Disaccharides Containing D-Galacto- or D-Fucofuranosides

Ronan Euzen

Unusual diglycosides composed of D-hexofuranosyl entities were prepared by a chemoenzymatic route using the -L-arabinofuranosidase, AbfD3. The required, unprotected monosaccharidic donors were first prepared according to multi-step syntheses. Since one goa ...

Synthesis of C-glycosides and C-linked disaccharides through carbonylative Stille coupling reactions

Peter Steunenberg

In the first part, we described the synthesis of C-(1'→1) and C-(1'→4) disaccharide precursors, which are readily obtained via the carbonylative Stille coupling of glucal and isolevoglucosenone derivatives. Tin glycals and triflates, derived from isolevogl ...
