DNA restriction-modification enzymes are enzymes involved in DNA restriction modification. They include DNA restriction endonucleases (restriction enzymes) and their companion modification methylase ...
Cellular RNAs are chemically modified by many RNA modification enzymes; however, often the functions of modifications remain unclear, such as for pseudouridine formation in the tRNA TΨC arm by the ...
In the early 1950s, experiments by two teams of researchers, Salvador Luria working with Mary Human and Joe Bertani working with Jean Weigle, showed that some strains of bacteria were more resistant ...
A research team is using the Linac Coherent Light Source (LCLS) to study an enzyme found in plants, bacteria and some animals that repairs DNA damage caused by the sun’s ultraviolet (UV) light rays. A ...
An important DNA modification is methylation, or the addition of a methyl group to the 5th carbon of cytosine. This forms 5-methylcytosine (5mC), typically associated with repression of gene ...
Sir2, an enzyme belonging to sirtuins, has been shown to be involved in the deacetylation of proteins. Researchers from the ...
DNA is often seen as the blueprint of life—carrying the code to govern the development and traits of an organism—but “there are things beyond the DNA sequence,” says Xiaoqi Feng, a plant geneticist at ...
