β-Lactams target penicillin-binding proteins (PBPs), a group of enzymes that are involved in cross-linking peptidoglycan in the bacterial cell wall and that cause cell lysis under standard laboratory ...

Milk from goats that were genetically modified to produce higher levels of a human antimicrobial protein has proved effective in treating diarrhea in young pigs, demonstrating the potential for food ...

Lysozyme is abundant in secretions such as saliva, human milk, tears and mucus, and is also known as N-acetylmuramide glycanhydrolase or muramidase. It is an antimicrobial enzyme that is generated by ...

LYSOZYME, a bacteriolytic enzyme discovered in 1922 by Sir Alexander Fleming, 2 is found in a number of biologic fluids. The enzyme is a basic protein of low molecular weight that lyses susceptible ...

Sir Alexander Fleming made two discoveries - the antibiotic penicillin, and the enzyme lysozyme - that have had a lasting impact on medical science. Now, one hundred years later, scientists have built ...

For any DLS system, its performance is based on the sample, for instance, the upper size limit may be > 5 μm for an emulsion, but < 1 μm for a high density particle since the analysis loses accuracy ...

A bacteria-digesting enzyme first discovered in human tears about a century ago may also have a not-so-helpful function: spurring chronic pain caused by nerve injury (Sci. Transl. Med. 2019, DOI: ...

Chinese researchers say they have genetically engineered dairy cows to produce milk more akin to human breast milk. The key is a particular protein — called lysozyme — that is abundant in human breast ...

An instrument which combines Raman spectroscopy with dynamic light scattering (DLS) can be used to study lysozyme’s unfolding and refolding processes under thermal stress conditions. Through the ...

Milk from goats that were genetically modified to produce higher levels of lysozyme, a human antimicrobial protein, has proved effective in treating diarrhea in young pigs and may one day be used to ...
