Investigating the role(s) of SufT and the domain of unknown function 59 (DUF59) in the maturation of iron–sulfur proteins
Comprehending biology at the molecular and systems levels is predicated upon understanding the functions of proteins. Proteins are typically composed of one or more functional moieties termed domains. Members of Bacteria, Eukarya, and Archaea utilize proteins containing a domain of unknown function (DUF) 59. Proteins requiring iron–sulfur (FeS) clusters containing cofactors are necessary for nearly all organisms making the assembly of functional FeS proteins essential. Recently, studies in eukaryotic and bacterial organisms have shown that proteins containing a DUF59, or those composed solely of DUF59, function in FeS protein maturation and/or intracellular Fe homeostasis. Herein, we review the current literature, discuss potential roles for DUF59, and address future studies that will help advance the field.
