Gavin King and a team of scientists used this atomic force microscope, bottom right, to study the movement of the E.coli proteins. Unlike previous studies where proteins were frozen, the atomic force microscope allows researchers to observe the proteins moving in a fluid environment that closely resembles their natural environment.

Directed evolution method can engineer synthetic nanoparticles

Mimicking natural evolution, directed evolution guides the synthesis of proteins with improved or new functions. The technique is powerful enough that it can engineer...
In this structural model for a beta-lactamase protein, catalytic residues are shown as spheres with those that are consistently highly frustrated along the entire beta-lactamase family shown in red and those for which the frustrated state is not conserved in yellow. The new work by scientists at Rice University, the University of Buenos Aires and the European Molecular Biology Laboratory suggests these enzymes, which must remain exposed to react with their targets, get a measure of protection from the somewhat-frustrated amino acids around them. The green lines represent minimal frustration, the red lines represent high frustration. The linear charts at top and bottom show the positions of the relevant amino acids on the protein chain and a measure of the conservation of energy over the entire beta-lactamases protein family.

Working proteins make good use of frustration

Proteins- active sites of enzymes- accelerates and guide biochemical reactions make life possible. To do this, their instructions have to conflict somewhat with the...

Scientists found a new way to create designer human proteins

Proteins are essential for life functions. Most human proteins are changed by a procedure called serine phosphorylation. Glitches in this procedure have been embroiled in...

High protein diet slightly increases heart failure risk in middle-aged men

A new study by the University of Eastern Finland suggests that intaking higher amounts of protein was associated with a slightly elevated risk for heart failure...

Treatment that Destroy Cancer Cells by Themselves

Cancer cells can grow any place in the body and crowds out normal cells. This causes problems in the part of the body where cancer started....
