The active site of ReAV in complex with L-Asn from the PDB entry 9g66, chain A (Pokrywka et al., 2025View full citation). The potential Ser48 and Ser80 nucleophiles from the two S–K tandems are in ball-and-stick representation. The oxyanion hole is marked by blue ovals. The Cd2+ cation (replacing Zn2+ in this variant) is marked by an orange sphere and water molecules are shown as small red balls. The most important hydrogen bonds are marked by black dashed lines and the coordination bonds around the cadmium cation are marked by blue dashes.
