image: Enzyme substrate specificity involving material conversion processes is pertinent to e.g. biochemistry, metabolic engineering, and environmental remediation; however, it is one of the most ...

Researchers from the University of Massachusetts, Amherst, say they have made an important discovery on how cells handle stress. Using bacterial cells, the team found that a damage-repairing enzyme, ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 106, No. 23 (Jun. 9, 2009), pp. 9215-9220 (6 pages) Altering the specificity of an enzyme requires precise ...

Researchers have made a major breakthrough earlier this year in the field of evolutionary conservation of molecular dynamics in enzymes. Their work points to potential applications in health, ...

For efficient aminoacylation, tRNAs carry the conserved 3′-terminal sequence C-C-A, which is synthesized by highly specific tRNA nucleotidyltransferases (CCA-adding enzymes). In several prokaryotes, ...

Researchers have found a new enzyme, taken from Flavobacterium akiainvivens, that has a much broader specificity than the current leading alternatives. Subscribe to our newsletter for the latest ...

Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are essential for life, as they play a crucial role in various biological processes, such as digestion, ...

Liver diseases are commonly diagnosed using serum enzyme assays, particularly for aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl ...
