TtuA is an oxygen-labile iron-sulfur protein that is involved in a post-transcriptional thiolation of RNA. The iron-sulfur cluster of TtuA is required for sulfurtransferase activity. The enzyme structure consists of three domains: a central catalytic domain and two Zn-fingers [1]. This entry represents the N-terminal Zn-finger domain that share a significant similarity to LIM domains.	Domain
