Cloning techniques produce FDA-approved antibiotic

...r goal now is to produce fosfomycin in Escherichia coli so that we can use various protein and metabolic engineering tools to manipulate the fosfomycin biosynthetic pathway," said Zhao, who also is an affiliate of the university's Institute for Genomic Biology. "Eventually, we should be able to produce fo...

Hope for major advance in fighting world killer disease

...tice in most Indian clinics is only to test for E. coli and Shigella if the child's symptoms have not responded to oral rehydration therapy by three days. The usual tests then take a further three days, by which time the disease may have progressed to a very serious stage. Our project has been to design a...

Engineer ramps up protein production, develops versatile viral spheres

...ell of a naturally occurring virus that infects E. coli bacteria. They are formed when 180 copies of the same protein assemble into a nanoscale soccer ball. "We think these little spheres, 27 nanometers in diameter, will form the basis for a new class of pharmaceuticals and a new class of materials," Sw...
