Crystal structure of ruthenocenecarbonitrile [PDF]

Acta Crystallographica Section E Crystallographic Communications, 2015
The molecular structure of ruthenocenecarbonitrile, [Ru(η5-C5H4C[triple-bond]N)(η5-C5H5)], exhibits point group symmetrym, with the mirror plane bisecting the molecule through the C[triple-bond]N substituent. The RuIIatom is slightly shifted from the η5-C5H4centroid towards the C[triple-bond]N substituent.

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long-standing annotation error. [PDF]

FEBS Open Bio
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...
