How nice, brown rice: Study shows rice bran lowers blood pressure in rats
...ment to the research that is new: using enzymes to clip
components of rice bran from its cell walls, rather than extracting a fraction with ethanol. “I think enzymatic treatment will be more suitable for applications if we’d like to use [rice bran as] functional food,?he said. The researchers?next step i...
UIC developing drug for SARS
...the virus to propagate. Two enzymes, or proteases, clip
the chain to release the individual proteins, the parts needed to assemble a mature virus. These two proteases -- called 3CLpro and PLpro -- are UIC's targets for drug therapy. "If we can block 3CLpro and probably PLpro, then we can stop the SARS v...
Protein offers way to stop microscopic parasites in their tracks
...ory known as rhomboid proteases, which are able to clip
off sections of proteins near the surface of the cell membrane. Using other rhomboid proteases as guides, Brossier identified genes for five rhomboid proteases in Toxoplasma. Scientists showed that the parasite used at least four of those genes to m...
