...Vancomycins is an amino acid-derived product," Evans says. "We have the chemistry in place for building any amino acid-based products--and rapidly...
Investigators studied the mechanism by which a mouse leukemia virus, MuLV, enters cells. They found that the receptor for this virus is a channel that allows positively charged amino acids to enter the cell. In further study, he and colleagues found that the gene encoding the sequence for this receptor was one whose structure allows specific molecules to pass through...
Computer-assisted searches comparing the receptor's amino acid sequence to other known proteins found that they were slightly similar to two amino acid importing proteins of yeast. Experiments with frog eggs proved that the protein did in fact play a role similar to that of these previously discovered proteins...
This was the ideal, anyway. But Big Science costs big bucks and breeds a more mundane and calculating kind of outlook. It takes hundreds of thousands of dollars a year to run a modern biological laboratory, with its electron microscopes, ultracentrifuges, amino-acid analyzers, Ph.D.s and technicians. The big bucks tend to go to big shots, like Baltimore, whose machines and underlings must grind out "results" in massive volume. In the past two decades, as federal funding for basic research has ebbed, the pressure to produce has risen to dangerous levels. At the same time, the worldly rewards of success...
...named because it would require manipulating objects , measured in billionths of a meter (nanometers). In Engines of Creation, the nanotechnologist's bible, K. Eric Drexler envisions a world in which everything from locomotives to cheeseburgers is assembled from molecular raw materials, much as proteins are created from their amino-acid building blocks by the machinery of a living cell...
