For example, an enzyme that catalyzed this reaction would be a lyase: ATP → cAMP + PPi Lyases differ from other enzymes in that they require only one substrate for the reaction in one direction, but two substrates for the reverse reaction.
For eksempel er et enzym, der katalyserer følgende reaktion, en lyase: ATP → cAMP + PPi Lyaser adskiller sig fra andre enzymer, idet de kun behøver ét substrat for reaktion i én retning, men to substrater for den modsatgående reaktion.
