The crystal structure of cytochrome c 6 from the brown alga H. fusiformis has been determined at 1.6 Å resolution. The amino-acid sequence and tertiary structure of H. fusiformis cytochrome c 6 were very similar to those of red algal cytochrome c 6 rather than those of green algal cytochrome c 6.

A combination of spectroscopic and crystallographic data have been used to identify the native metal-ion preference of GpdQ. These data suggest that GpdQ is a homobinuclear non-haem iron enzyme.

A crystal structure of zebrafish Plk1 reveals the binding of an extended ATP-competitive inhibitor that targets the adaptive pocket and helps to order the activation segment of the kinase. The conformation of the segment resembles that observed in a nonphosphorylated ligand-free wild-type kinase domain.
