PPU	4	PUROMYCIN-5'-MONOPHOSPHATE C22 H30 N7 O8 P NYICMZBLMICLBS-NVWDDTSBSA-N	Poseview Image of PPU in 1KQS Help Black dashed lines indicate hydrogen bonds, salt bridges, and metal interactions. Green solid line show hydrophobic interactions and green dashed lines show π-π and π-cation interactions. Source Information Interactions are determined by geometric criteria as described in K. Stierand, M. Rarey (2010), Drawing the PDB: Protein-ligand complexes in two dimensions, ACS Med. Chem. Lett., DOI: 10.1021/ml100164p. Ions and some metal complexes are excluded, as well as cases where no interaction profile could be generated. Poseview diagrams can be calculated for approximately 92% of the remaining complexes in the PDB. PoseView is developed at the Center for Bioinformatics Hamburg and jointly provided with BioSolveIT as a community service at the PDB. A stand-alone version is provided by BioSolveIT.
