Active-site structure of Psy-Lig-A. The nucleotide cofactor is depicted and labelled in green and the sulfate ion is in yellow. Lys25 which is covalently attached to the AMP is labelled in bold; all residues making contacts with the cofactor and ion are shown as purple sticks. Secondary-structural elements of the AD domain are labelled in light purple and correspond to the notation used in Fig. 2[link].
