ErpA is required for respiratory growth; erpA mutants have reduced ubiquinone and menaquinone; ErpA can transfer Fe-S clusters to apo-IspG in vitro (Loiseau, 2007). iscA, sufA, and erpA are paralogs; nfuA is a possible HT gene with an N-terminal domain homologous to sufA and an additional thioredoxin-like C-terminal domain.
