The gastrointestinal microbiota composition is influenced by bile salts and in turn, bile salts themselves are chemically modified in the gut by bacterial enzymes such as bacterial bile salt hydrolase (BSH).
The presumption follows that a similar approach targeting bacterial enzymes may counteract the efflux mechanism common in Gram-negative resistance.
Using engineered viruses as gene carriers, Harvey and his colleagues at the University of Georgia in Athens inserted the DNA blueprint for a bacterial enzyme called beta-lactamase into embryos of white leghorn chickens.
Everything else on the antibiotic gives it useful properties, such as water solubility, resistance to metabolism (antibiotics would be no good if they were broken down in the intestines) and the ability to fit snugly into the active site of the bacterial enzyme it targets.
Unlike bleach and soap that destroy and dislodge germs, triclosan works by interfering with a specific bacterial enzyme, which not all bacteria have.
In the 1970s, the bacterial enzyme amylase replaced acid conversion in processing corn starch to glucose.
Anacor Pharmaceuticals (NASDAQ:ANAC) announced today that it has amended and expanded its research and development collaboration with GlaxoSmithKline (GSK) to provide GSK the option to extend its rights around the bacterial enzyme target leucyl-tRNA synthetase (LeuRS), as well as to add new programs for tuberculosis (TB) and malaria using Anacor's boron chemistry platform.
A team of researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have determined how the bacterial enzyme known as Cas9, guided by RNA, is able to identify and degrade foreign DNA during viral infections, as well as induce site-specific genetic changes in animal and plant cells.
To make corn syrup commercially, instead of using an acid, a mixture of corn starch and water is treated first with alpha amylase, a bacterial enzyme that breaks the starch down into oligosaccharides, followed by the addition of gammaamylase, an enzyme isolated from the Aspergillus fungus that converts some of the oligosaccharides to glucose.
