Microbes evolve new traits quickly, but not quickly enough for scientists eager to direct the evolution of microbes toward desirable ends. Usually, scientists must wait for chance occurrences to ...

All forms of life depend on enzymes—without them most biochemical reactions would proceed too slowly to sustain the processes of life. Enzymes function by binding to a compound known as a substrate.

A METHOD for the concentration of enzymes and other biological colloids was recently described by Guy E. Youngbourg 1. By this method the volume of the active solution is reduced by dialysing it ...

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 challenging ...

On page 1115 of this issue, Robert Sauer and his colleagues offer an insight into what makes molecular machines work. Their focus is an enzyme called ClpX, which unfolds proteins and prepares them for ...

This article describes a simple method to determine the optimum pH for the activity of one enzyme in a coupled enzyme assay. Decoupling of the two-step reaction is achieved by heat denaturing the ...

The best enzyme for de novo DNA synthesis may be one that is denied all its enzymatic attributes. Yes, it acts on a specific substrate. Yes, it catalyzes a chemical reaction. No, it does not exit the ...

Over the past five years or so we've seen some important breakthroughs demonstrating how enzymes can be used to break down common plastics, such as the PET used for everything from drink bottles to ...

A new type of DNA editing enzyme lets scientists directly and permanently change single base pairs of DNA from A*T to G*C. The process could one day enable precise DNA surgery to correct mutations ...

Things are heating up in the world of CRISPR gene editing. With the first human trials using the experimental technology set to commence soon, the research community has been facing a series of ...

To figure out how life on Earth started, scientists must recreate the world as it was, or at least know the ins and outs of our primordial planet. This week, scientists moved in that direction, ...
