The current enzymes wiki excerpt states:
Enzymes are organic catalysts. Most enzymes are proteins, although a few are catalytic RNA molecules. Catalysts speed up the rate of a reaction by lowering the activation energy barrier and are not consumed in the reaction.
However, in the light of findings that suggest "some enzymes work by preventing reactions that are not wanted rather than promoting reactions that are wanted", it would be prudent to change the tag wiki excerpt to something that is not in disagreement with these findings...but also doesn't wholeheartedly embrace them (until they've been soundly established).
Hence I propose a "neutral" tag wiki excerpt (of sorts):
Enzymes are macromolecular biological catalysts that alter the rate of a reaction, and are not consumed in the process. Most enzymes are proteins, although a few are catalytic RNA molecules.
So, do I have the green-light to go ahead with this edit?
Based on @Jan's suggestion, perhaps it would be better to edit the wiki excerpt to include a brief definition and indicate conditions for usage. So, the improved version will look like,
Enzymes are macromolecular biological catalysts that alter the rate of a reaction. Use this tag for question regarding enzyme kinetics, classification and action.
