Bacillus subtilis PgcA moonlights as a phosphoglucosamine mutase in support of peptidoglycan synthesis

Phosphohexomutase superfamily enzymes catalyze the reversible intramolecular transfer of a phosphoryl moiety on hexose sugars. Bacillus subtilis phosphoglucomutase PgcA catalyzes the reversible interconversion of glucose 6-phosphate (Glc-6-P) and glucose 1-phosphate (Glc-1-P), a precursor of UDP-glucose (UDP-Glc). B. subtilis phosphoglucosamine mutase (GlmM) is a member of the same enzyme superfamily that converts glucosamine... Читать дальше...

Large-scale, dynamin-like motions of the human guanylate binding protein 1 revealed by multi-resolution simulations

by Bogdan Barz, Jennifer Loschwitz, Birgit Strodel

Guanylate binding proteins (GBPs) belong to the dynamin-related superfamily and exhibit various functions in the fight against infections. The functions of the human guanylate binding protein 1 (hGBP1) are tightly coupled to GTP hydrolysis and dimerization. Despite known crystal structures of the hGBP1 monomer and GTPase domain dimer, little is known about the dynamics of hGBP1. To gain a mechanistic understanding of hGBP1, we performed sub-millisecond... Читать дальше...

A simulation of the random and directed motion of dendritic cells in chemokine fields

Dendritic cells (DCs) are the most effective professional antigen-presenting cell. They ferry antigen from the extremities to T cells and are essential for the initiation of an adaptive immune response. Despite interest in how DCs respond to chemical stimuli, there have been few attempts to model DC migration. In this paper, we simulate the motility of DCs by modeling the generation of forces by filopodia and a force balance on the cell. Читать дальше...

A hormone receptor pathway cell-autonomously delays neuron morphological aging by suppressing endocytosis

by Claire E. Richardson, Callista Yee, Kang Shen

Neurons have a lifespan that parallels that of the organism and are largely irreplaceable. Their unusually long lifespan predisposes neurons to neurodegenerative disease. We sought to identify physiological mechanisms that delay neuron aging in Caenorhabditis elegans by asking how neuron morphological aging is arrested in the long-lived, alternate organismal state, the dauer diapause. We find that a hormone signaling pathway, the abnormal DAuer... Читать дальше...

U.S. Energy Secretary Perry Dismisses Report He’s Resigning

Oilprice.com 
En

U.S. Secretary of Energy Rick Perry denied on Monday reports that he was preparing to resign next month, saying that he doesn’t plan to go anywhere. Secretary Perry is planning to hand in his resignation in November, Politico reported last week, citing three unnamed sources in the know. According to Politico’s sources, Secretary Perry has been considering resigning for several months now, and his indirect involvement in the impeachment proceedings against U.S. President Donald Trump may have helped him make his mind.

Brimming Storage And No Buyers: Venezuela’s Oil Production Tanks

Oilprice.com 
En

Venezuela’s oil production took another hit in recent days, as the country struggles with brimming storage tanks and no buyers. PDVSA slashed output in the Orinoco Belt to just 200,000 bpd, according to Bloomberg, after averaging roughly double that for much of this year. The lack of space in storage forced production cuts, including at joint venture projects, where output has been more stable. Sources told Bloomberg that the Sinovensa blending facility would be idled for at least a week. Venezuela’s... Читать дальше...
