Abstact

SufU is a zinc-containing protein involved in mobilization of sulfur from SufS for iron-sulfur cluster biogenesis of Bacillus subtilis. Structural basis for the sulfur transfer in SufS-SufU complex was revealed. A zinc-ligand exchange reaction upon SufS-SufU complexation provides a free thiol from Cys41 of SufU as a sulfur acceptor.
