Enzymes are very efficient and specific catalyst proteins which react with 1 or few types of substrates in biochemical reactions and are responsible for bringing about almost all of the chemical reactions in living organisms. Enzymes speed up reactions by providing an alternative reaction pathway of ...
Biocatalysts have many benefits for speeding up specific transformations, but the chemistry used by naturally occurring catalysts is limited. Pioneering work in 2016 used directed evolution to create heme-dependent enzymes able to form new silicon–carbon bonds, showcasing the approach’s power to atta...
The substrate is bound to a specific region of the enzyme called the active site. Most enzymes are highly selective in their binding of substrates. Indeed, the catalytic specificity of enzymes depends in large part on the specificity of the binding process. Furthermore, the control of enzymatic...
Naturally occurring DNA polymerases can amplify DNA efficiently via PCR, but they cannot utilize C2′-modified substrates to make non-natural nucleic acids. Such C2′-modified nucleic acids are of interest as they are resistant to nucleases. Now, a Stoffel fragment DNA polymerase has been evolved...
Enzymes differ from many other natural substances in their fragile macromolecular polyvalent amphoteric nature and from other proteins in their specific topography, reflecting their particular activities. The special, very susceptible, and complicated structure of enzymes must be kept in mind when methods ...
Among methods available to investigate DNA methylation state, restriction enzymes are a popular tool due to their availability and ease of use. Some restriction enzymes’ recognition sites contain CpG sequences, and the enzyme...
Smith and Daniel Nathans shared the 1978 Nobel Prize for Medicine and Physiology for their discovery of restriction enzymes and their application to molecular genetics. Because of the ability of these enzymes to cleave DNA at specific recognition sites, they have continued to play a fundamental role...
and biased subset, enzymes are quite specific catalysts, and therefore most of the potential secondary substrates are not included for the majority of enzymes. Thus, we assumed that the frequency of incorrectly created negative labels is sufficiently low to not adversely affect model performance. ...
For simplicity, donor substrates and nucleotide products are omitted. The structure underlined in red was not found among the observational data set (Supplementary Table S1). Full size image Bifunctional enzymes Glycosyltransferases (GTs) are multi-specific, acting on a range of acceptors according to...
