Schematic presentation of ligand binding and interactions in the active site of PfSpdS. (a) The complex with putrescine and MTA. (b) The complex with spermidine and MTA. (c) The complex with 4MAN and dcAdoMet. (d) The complex with 4AMA and MTA. The amino-acid side chains and bound compounds are shown in stick representation (N atoms, blue; O atoms, red; C atoms, green; S atoms, yellow). Dashed lines represent potential hydrogen bonds. |
