Nonetheless, many potential applications await the development of enzymes that can catalyze difficult reactions involving chemical transformations not encountered in the biological world.

Figure 1: Active site structures of representative nonheme iron enzymes with a 2-His-1-carboxylate facial triad and the reactions they catalyze. A comparison of the primary sequence information of ...

However, it is safe to say that no enzyme is perfect in the sense of catalyzing only a single reaction with a single substrate. For enzymes such as P450s and glutathione S-transferases that are ...

Enzymes in metabolic pathways are superb catalysts, accelerating chemical reactions by up to 16 orders of magnitude. Many enzymes also catalyze adventitious secondary reactions, simply because active ...

The diagram below shows how an enzyme catalyses the breakdown of one substrate into two products.

Others are protein molecules, called enzymes, that are contained in microorganisms. Still others are naturally occurring solids, such as manganese or iron ixides. No matter what the catalyst's ...

Viral proteases utilize many different catalytic mechanisms and oligomeric assemblies. They are also an interesting example of enzymes that can catalyze an intramolecular reaction as well as an ...

Biocatalysis is a process that uses enzymes as natural catalysts to carry out chemical reactions. Scientists at The University of Manchester and AstraZeneca have developed a new biocatalytic ...
