BLOOD coagulation, which is a special case of protein denaturation, has been found to be a chain reaction by which a new reacting substance is formed 1. By the action of heat on a mono-disperse ...

The signs of liver failure occur in stages, starting with early symptoms such as nausea, vomiting, itchiness, and yellowing of the eyes or skin (jaundice). As it progresses, you may experience loss of ...

Aluminum (Al) toxicity has been recognized as the factor that most limits crop production in acid soils. Studies indicate that acid soils constitute approximately 50% of cultivated soils in the world.

Now, a new study from Scripps Research demonstrates a proof of concept for a new strategy: engineering proteases—enzymes that cut proteins at specific sites—to selectively degrade these ...

PCR was conducted as follows: 3 min of denaturation at 95°C; 27 cycles of 30 s at 95°C, 30 s for annealing at 55°C, and 45 s for elongation at 72°C; and a final extension at 72°C for 10 min. The ...

Proteases are degradative enzymes found in plants, microorganisms, and animals; they hydrolyze proteins into peptides and amino acids (1). Proteases present in milk (plasmin, elastase, cathepsin D, ...

In this bacterium, an enzyme called RecJ performs part of the first step in the repair of DNA double-strand breaks by progressively shortening one end of a DNA strand. Cheng et al. have now used ...
