Ferritin-like superfamily of diiron-containing four-helix-bundle proteins; Ferritin-like, diiron-carboxylate proteins participate in a range of functions including iron regulation, mono-oxygenation, and reactive radical production. These proteins are characterized by the fact that they catalyze dioxygen-dependent oxidation-hydroxylation reactions within diiron centers; one exception is manganese catalase, which catalyzes peroxide-dependent oxidation-reduction within a dimanganese center. Diiron-carboxylate proteins are further characterized by the presence of duplicate metal ligands, glutamates and histidines (ExxH) and two additional glutamates within a four-helix bundle. Outside of these conserved residues there is little obvious homology. Members include bacterioferritin, ferritin, rubrerythrin, aromatic and alkene monooxygenase hydroxylases (AAMH), ribonucleotide reductase R2 (RNRR2), acyl-ACP-desaturases (Acyl_ACP_Desat), manganese (Mn) catalases, demethoxyubiquinone hydroxylases (DMQH), DNA protecting proteins (DPS), and ubiquinol oxidases (AOX), and the aerobic cyclase system, Fe-containing subunit (ACSF).

tRNA-(MS[2]IO[6]A)-hydroxylase (MiaE); This family consists of several bacterial tRNA-(MS(2)IO(6)A)-hydroxylase (MiaE) proteins. The modified nucleoside 2-methylthio-N-6-isopentenyl adenosine (ms2i6A) is present at position 37 (3' of the anticodon) of tRNAs that read codons beginning with U except tRNA(I,V Ser) in Escherichia coli. Salmonella typhimurium 2-methylthio-cis-ribozeatin (ms2io6A) is found in tRNA, probably in the corresponding species that have ms2i6A in E. coli. The miaE gene is absent in E. coli, a finding consistent with the absence of the hydroxylated derivative of ms2i6A in this species.

MiaE tRNA-modifying nonheme diiron monooxygenase, ferritin-like diiron-binding domain; MiaE is a nonheme diiron monooxygenase that catalyzes the posttranscriptional allylic hydroxylation of a modified nucleoside in tRNA called 2-methylthio-N-6-isopentenyl adenosine (ms2i6A). ms2i6A is found at position 37, next to the anticodon at the 3' position in almost all eukaryotic and bacterial tRNA's that read codons beginning with uridine. The miaE gene is absent in Escherichia coli, a finding consistent with the absence of the hydroxylated derivative of ms2i6A in this species.

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
