Proteins in this family have been identified as a component of the higher eukaryotic NADH complex. In Saccharomyces cerevisiae, the Isd11 protein has been shown to play a role in Fe/S cluster biogenesis in mitochondria. We have named this family LYR after a highly conserved tripeptide motif close to the N-terminus of these proteins. Length = 59

This is a family of proteins carrying the LYR motif of family Complex1_LYR, pfam05347, likely to be involved in Fe-S cluster biogenesis in mitochondria. Length = 61
>PF05347 Complex1_LYR: Complex 1 protein (LYR family); InterPro: IPR008011 This family of short proteins includes proteins from the NADH-ubiquinone oxidoreductase complex I
The family includes the B14 subunit from bovine NADH-ubiquinone oxidoreductase B14 subunit Q02366 from SWISSPROT, and the B22 subunit from the human enzyme Q9Y6M9 from SWISSPROT. The family has been named LYR after a highly conserved tripeptide motif close to the N terminus of these proteins. Members of this family also found in yeast which do contain this complex. In these organisms they are believed to be be required for iron-sulphur custer biogenesis.
