Hijacking host cell vesicular transport: New insights into the nutrient acquisition mechanism of Chlamydia

Virulence
Chlamydia infection is an important cause of public health diseases, and no effective vaccine is currently available. Owing to its unique intracellular lifestyle, Chlamydia requires a variety of nutrients and substrates from host cells, particularly ...

A short peptide derived from late embryogenesis abundant proteins enhances acid tolerance in Escherichia coli via modulation of two‐component regulatory systems

The FEBS Journal, EarlyView.
Expression of the LEA‐K peptide in E. coli BL21 (DE3) improved bacterial viability under acidic stress (pH4), suggesting a protective function. RNA‐sequencing of LEA‐K‐expressing vs. non‐expressing cells revealed 283 differentially expressed genes (DEGs). In silico docking linked LEA‐K to two‐component systems (TCS) proteins (Rcs, BtsS/R, and EnvZ/OmpR)

Borrelial phosphomannose isomerase as a cell surface localized protein that retains enzymatic activity and promotes host-pathogen interaction

mBio
All organisms produce an intracellular Zn2+-dependent enzyme, phosphomannose isomerase (PMI) or mannose-6 phosphate isomerase, that catalyzes the reversible conversion of mannose-6-phosphate and fructose-6-phosphate during sugar metabolism and ...

Protein nanoparticles assemble in plants, display antigenic viral peptides, and produce an epitope‐specific immune response

The FEBS Journal, EarlyView.
Current methods to control porcine reproductive and respiratory syndrome, a disease affecting pigs, are insufficient and a safer, more effective vaccine is needed. This study describes the design and plant production of a self‐assembling protein nanoparticle vaccine candidate against this disease.

Novel particulate vaccine candidates recombinantly produced by pathogenic and nonpathogenic bacterial hosts : a thesis presented in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Microbiology at Massey University, Manawatu, New Zealand. [PDF]

, 2017
Polyhydroxyalkanoates (PHAs) are biopolyesters synthesized as small spherical cytoplasmic inclusion bodies by a range of bacteria. Recently, PHA beads have been investigated for use as a vaccine delivery platform by using engineered heterologous ...

The fc fragment of IgMs binds C1q to activate the first step of the classical complement pathway, while inhibiting complement‐dependent cytotoxicity

The FEBS Journal, EarlyView.
Multimeric IgM‐fragment crystallizable region (Fc) fragments retain the ability to bind C1q and initiate the classical complement pathway, leading to C4 activation and deposition in vitro. However, the Fc cores can also inhibit complement‐dependent cytotoxicity by competing with surface‐bound antibodies for C1q engagement.

RNF13 is a previously undescribed interactor of iduronate 2‐sulfatase that modifies its glycosylation and maturation

The FEBS Journal, EarlyView.
Iduronate 2‐sulfatase (IDS; purple) is expressed as a precursor protein that goes through multiple steps of maturation, modification, and trafficking to become an active lysosomal enzyme that degrades glycosaminoglycans. Our study shows that the transmembrane ubiquitin ligases RNF13 (orange) and RNF167 (pink) heterodimerize, affecting IDS intracellular

Late Stage Mannan Metabolism in Cellvibrio japonicus Requires the Combined Action of a Mannosyl‐Glucose Phosphorylase and a Mannobiose Epimerase

Molecular Microbiology, EarlyView.
Model for the non‐PTS utilization of manno‐oligosaccharides by Cellvibrio japonicus. The Mgp130A and EpiA enzymes are essential for the utilization of mannose residues. ABSTRACT Manno‐oligosaccharides and their metabolism play important roles in gut health, pharmaceutical development, and renewable chemical production.
