FIG. 4. The atoms are colored as gray, blue, red, and yellow for carbon, nitrogen, oxygen, and phosphor, respectively and panels a and b were produced using Quanta. a, stereo view of electron density (2F[o] - F[c] coefficients, 1.0 level) for AMP-PNP with two bound magnesium ions. b, the binding interactions of AMP-PNP phosphates with Pim-1. Lys169 does not bind AMP-PNP in Pim-1, contrasting with what is observed in other kinases. Single letter amino acid abbreviations are used with position numbers.
