Here we describe the process and some of the current ... rather than 'entities', and as such an enzyme's function is described by its overall activity on a substrate, such as amino ...

Enzyme activity measures how fast an enzyme can change a substrate into a product ... One example is phenylketonuria (or PKU), a rare inherited disease where the body lacks the enzyme to process ...

although some RNA molecules called ribozymes also exhibit enzymatic activity. Enzymes are biological catalysts that lower the activation energy of chemical reactions, allowing them to proceed at a ...

The adsorption of proteins on surfaces — a process known as fouling — is ... is stable and has a well-sustained enzyme activity over a broad range of conditions. Researchers working on medical ...

A new approach to enzyme engineering has overcome many of the operating challenges associated with large-scale bio-based ...

Scientists have long been curious about a mysterious part of our DNA called heterochromatin, often called the “dark side of ...

A demonstration of the key points of the required practical to investigate the effect of pH on enzyme activity for GCSE ... This film slows the process down, exploring each step.

This is shown in the graph below. In the graph above, as the pH increases so does the rate of enzyme activity. An optimum activity is reached at the enzyme’s optimum pH, pH 8 in this example.

About 98% of lignin created as a forestry by-product from plants is discarded, but a new enzyme could be the key to ...

Using computational tools and virtual screening, researchers at the Center for Redox Processes in Biomedicine (Redoxoma) have identified new inhibitors of the enzyme human 15-lipoxygenase-2 (h15-LOX-2 ...
