One of the most important classes of human enzymes are protein kinases — signaling molecules that regulate nearly all cellular activities, including growth, cell division, and metabolism. Dysfunction ...
Researchers at MIT’s McGovern Institute for Brain Research have discovered a bacterial enzyme that they say could expand scientists’ CRISPR toolkit, making it easy to cut and edit RNA with the kind of...
Healthy skin has a bacterial shield to protect against germs: the microbiome. This complex assembly of microorganisms was previously believed to be difficult to decipher. A team of researchers has now...
Scientists studying the biochemistry of plant cell walls have identified an enzyme that could turn woody poplar trees into a source for producing a major industrial chemical. The research could lead t...
华南理工大学酶工程课件 Enzyme enignnering。
Assessment of seminal oxidative stress indicators is emerging as a valuable prognostic tool in assisted reproductive technology. We investigated levels of oxidative stress caused by reactive oxygen s...
A dawning field of research, artificial biology, is working toward creating a genuinely new organism. At Princeton, chemistryprofessor Michael Hecht and the researchers in his lab are d...
The human body has two primary kinds of fat—white fat, which stores excess calories and is associated with obesity, and brown fat, which burns calories in order to produce heat and has garnered intere...

A team of researchers at the University of Delaware has discovered a new function for an enzyme that has long been known to have a central role in bacterial metabolism.Maciek Antoniewicz, Centennial J...
Acyltransferase (AT) domains of polyketide synthases (PKSs) select extender units for incorporation into polyketides and dictate large portions of the structures of clinically relevant natural product...
New research by scientists from the University of Chicago demonstrates that the mammalian enzyme ALKBH1 can remove molecular modifications from transfer RNA, causing a measurable effect on protein tra...
Extended hydrogen bond networks are a common structural motif of enzymes. A recent analysis proposed quantum delocalization of protons as a feature present in the hydrogen bond network spanning a tria...
Enzymes use protein architectures to create highly specialized structural motifs that can greatly enhance the rates of complex chemical transformations. Here, we use experiments, combined with ab init...
Pauling's suggestion that enzymes are complementary in structure to the activated complexes of the reactions they catalyze has provided the conceptual basis to explain how enzymes obtain their fantast...
Extensive structural studies of enzymes have revealed that biological catalysis occurs within sequestered active site crevices, where reacting substrates are surrounded by an anisotropic and chemicall...
