Fingerprinting redox and ligand states in haemprotein crystal structures using resonance Raman spectroscopy

High-resolution X-ray crystallography has been effectively combined with resonance Raman spectroscopy to `fingerprint' and validate different redox and ligand states in structures of Alcaligenes xylosoxidans cytochrome c'.

The structure of a class 3 nonsymbiotic plant haemoglobin from Arabidopsis thaliana reveals a novel N-terminal helical extension

The first crystal structure of a class 3 nonsymbiotic plant haemoglobin is reported to 1.77 Å resolution. The structure revealed a novel N-terminal helical extension that participates extensively in the dimeric interface.
