5.1.3.8 | ATP | allosteric activation | Acaryochloris marina | |
5.1.3.8 | ATP | allosteric activation, ATP has a more pronounced effect on the Km for the substrate than on the enzyme activity. The enzyme shows 20% of maximal activity without ATP. At high substrate concentrations of 200 mM and without ATP, the enzyme reaches up to 32% of the activity measured with ATP in excess | Trichormus variabilis | |
