2.7.8.7 Mg2+ - 645395, 645402, 645403, 645407, 645410, 761359 2.7.8.7 Mg2+ contains Mg2+ 721646 2.7.8.7 Mg2+ dependent on 723567, 738930, 739435 2.7.8.7 Mg2+ dependent on, binding structure, overview. The edge strands beta4 and beta6 of the two beta-sheets provide the binding site for the CoA diphosphate and associated Mg2+ ion. The active site in Mtb-PptT is formed in the shallow cleft between the two domains, where CoA and Mg2+ are bound 738932 2.7.8.7 Mg2+ maximal activity at 0.025 mM 486864 2.7.8.7 Mg2+ nonessential for binding of coenzyme A (CoA) 691732 2.7.8.7 Mg2+ required 723610, 737325, 737568, 737715, 738470, 738868 2.7.8.7 Mg2+ required for activity 721530 2.7.8.7 Mg2+ requires Mg2+ or Mn2+ for activity, Km for Mg2+ 3.0 mM 645393, 645397 2.7.8.7 Mn2+ - 645395
