4Fe-4S double cluster binding domain-containing protein
HEAT repeat domain-containing protein
This family includes multiple HEAT repeats. (from Pfam)
QueG-associated DUF1730 domain-containing protein
This domain of unknown function occurs in Epoxyqueuosine reductase QueG, an iron-sulfur cluster-binding protein, together with the 4Fe-4S binding domain (Pfam:PF00037). QueG catalyses the conversion of epoxyqueuosine (oQ) to queuosine (Q), which is a hypermodified base found in the wobble positions of tRNA(Asp), tRNA(Asn), tRNA(His) and tRNA(Tyr) [1]. [1]. 21502530. Discovery of epoxyqueuosine (oQ) reductase reveals parallels. between halorespiration and tRNA modification.. Miles ZD, McCarty RM, Molnar G, Bandarian V;. Proc Natl Acad Sci U S A. 2011;108:7368-7372. (from Pfam)

epoxyqueuosine reductase catalyzes the conversion of epoxyqueuosine (oQ) to queuosine (Q), which is a hypermodified base found in the wobble positions of tRNA(Asp), tRNA(Asn), tRNA(His) and tRNA(Tyr)
tRNA epoxyqueuosine(34) reductase QueG
This model was rebuilt to exclude archaeal homologs, now that there is new information that bacterial members are epoxyqueuosine reductase, QueG, involved in queuosine biosynthesis for tRNA maturation.
