Fig. 2From: The crystal structure of JNK from Drosophila melanogaster reveals an evolutionarily conserved topology with that of mammalian JNK proteinsAMP-PNP bound to Drosophila JNK. F o-F c omit electron density map (contoured at 4σ) is shown in grey for the bound DJNK-AMP-PNP (magenta stick model). Amino acid residues crucial for the ATP binding of DJNK are shown in cyan. Two Mg2+ ions are shown as orange balls. Hydrogen bonds are indicated as dashed linesBack to article page
