The biosynthesis of iron sulfur (Fe-S) clusters in Bacillus subtilis is mediated by a SUF-type gene cluster, consisting of the cysteine desulfurase SufS, the scaffold protein SufU, and the putative chaperone complex SufB/SufC/SufD. Here, we present the high-resolution crystal structure of the SufS homodimer in its product-bound state (i.e., in complex with pyrodoxal-5'-phosphate, alanine, Cys36...

Autism and Tourette syndrome are complex enigmatic disorders. Both are childhood neurological syndromes affecting behavior, social interaction, movement, and language. Like many complex disorders, autism and Tourette syndrome are thought to have complex genetic and environmental etiologies. Similarly, autoimmune and inflammatory (AI) disorders have complex multigenic and environmental origins. ...

In this paper we report and discuss the results of a radio survey in the A3571 cluster complex, a structure located in the Shapley Concentration core, and formed by the three clusters A3571, A3572 and A3575. The survey was carried out simultaneously at 22 cm and 13 cm with the Australia Telescope Compact Array, and led to the detection of 124 radio sources at 22 cm. The radio source counts in t...

ABSTRACT Typical globular clusters (GCs – young and old) host stellar populations with little or no star-to-star variations in heavy elements (e.g. Ca, Fe) nor age. Nuclear star (NSCs), on the other hand, complex that show multimodal distributions Fe often age, presumably due to their unique location at centre of a large galactic potential well. However, recently new class have been discovered,...
