A smurfin' good structure: The 1.16 Å resolution crystal structure of ranasmurfin, a blue protein extracted from the foam nests of the Malaysian tree frog Polypedates leucomystax, reveals unusual posttranslational chemical modifications. The chromophore involves an extended Zn-coordinated four-residue (Lys-Tyr-Tyr-Lys) inter-subunit cross-link of a kind not previously reported
