Programmable swarmbots help make flexible biological tools

Biomedical engineers at Duke University have developed a new platform to create biologic drugs using specially engineered bacteria that burst and release useful proteins when they sense that their capsule is becoming too ...

Structure of protein nanoturbine revealed

Cells rely on protein complexes known as ATP synthases or ATPases for their energy needs. Adenosine triphosphate (ATP) molecules power most of the processes sustaining life. Structural biologist Professor Leonid Sazanov and ...

Experiments illuminate key component of plants' immune systems

Plants, like humans and animals, have over millions of years evolved complex immune systems that fend off invading pathogens. But unlike many animals, plants lack adaptive immunity conferred by antibodies. This means each ...

A new protein spin labelling technique

Site-directed spin labelling (SDSL) used in combination with electron paramagnetic resonance (EPR) spectroscopy has been a tried and trusted technique for elucidating the structure, function and dynamics of proteins and protein ...

Gatekeepers of the genome

Transcription factors control gene activation in cells. By binding to specific segments of DNA, they enable the blueprints that code for cellular proteins to be produced. But how are such factors themselves regulated?

Protein quality control and mitochondria

Protein aggregates are toxic for mitochondrial function, and thus disrupt the supply of chemical energy to their host cells. An LMU team has characterized a protein complex that prevents the build-up of such deposits in the ...

Turning up the heat on pathogenic bacteria

Pathogenic bacteria come alive at the metabolic level when they enter the warmth of the human gut, firing up genes that encode toxins and other compounds harmful to our bodies. A KAUST-led study shows how a critical bacterial ...
