A novel antifungal antibiotic, formamicin, was isolated from the culture broth of Saccharothrix sp. MK27-91F2. The absolute structure of formamicin was determinated by spectroscopic and X-ray crystallographic analysis and degradation study.

This paper reports a three-dimensional EXAFS refinement of the Mo coordination sphere of the FeMoco cluster of the dithionite-reduced MoFe protein from Klebsiella pneumoniae nitrogenase (Kp1) using the 1.6 A-resolution crystallographic coordinates. At this resolution, the positions of the heavy (Fe and S) atoms of the cluster are well determined and there is excellent agreement between the crys...

A new class of solution-processable small molecule organic semiconductors that are capable functioning at low operating voltages (?6 V) have been developed and their structure–activity correlation has studied using crystallographic analyses.
