In the left, a sketch of the human digestive tract, with pills in the stomach. On the right, a magnifying glass shows a model of the peptide transporter 1 in the cell membrane in the intestine wall. The pills from the left part of the image form a path made of smaller particles, and individual molecules represented by structural formulas. The path connects the intestine on the left to the opening of PepT1 and continues on the other side of the intestine wall. Individual drug molecules enter PepT1 and are transported to the other side of the cell membrane.

Structure of a promiscuous protein will help scientists design better drugs

Science Scientists at EMBL Hamburg determined the molecular structure of Peptide Transporters 1 and 2. The findings will enable developing drugs that more efficiently pass from the gut to target tissues.

SARS-CoV-2 is represented as a sphere with spike proteins poking out of its surface, which give it a corona-like appearance. The spike proteins resemble triangular ‘bushes’ with three tips at the top. In the background, a cell surface is visible with ACE2 proteins poking out of it in many places. The virus is about to attach to the cell surface. The sybodies, represented as tiny V-shaped structures, bind to the viral spike proteins at their tips.

Scientists identify synthetic mini-antibody to combat COVID-19

Science By screening hundreds of sybodies (synthetic mini-antibodies), scientists have identified one that might stop SARS-CoV-2 from infecting human cells. This work, which holds promise for treating COVID-19, was conducted by EMBL Hamburg and collaborators from the Centre for Structural Systems Biology…

Molecular structure of essential light chain protein in Plasmodium glideosome. The atoms connected by bonds are symbolised by short connected lines. They are surrounded by electrons – the electron density is depicted as shapes resembling clouds. Water molecules are visible in several places as red spots. The data used to create this 3D model were obtained using X-ray crystallography at Petra III beamline, at EMBL Hamburg.

How deadly parasites ‘glide’ into human cells

Science A group of scientists led by EMBL Hamburg’s Christian Löw provide insights into the molecular structure of proteins involved in the gliding movements through which the parasites causing malaria and toxoplasmosis invade human cells.

Exploring synthetic antibodies to stop coronavirus

Science Scientists at EMBL Hamburg and Karolinska Institutet Stockholm aim to find synthetic antibodies – known as nanobodies – that bind a surface protein of the novel SARS-CoV-2 coronavirus. Nanobodies could prevent the virus from entering human cells and causing COVID-19.
