Summary
NfuA can transfer its [4Fe-4S] cluster into apo-aconitase AcnA and nfuA mutants have reduced survival to oxidative and iron stress (Angelini, 2008). nfuA(yhgI) is required for the utilization of DNA as a carbon source and is a H. influenzae competence protein ComG homolog (Palchevskiy, 2006). nfuA(gntY) does not have a role in gluconate metabolism (T.Conway, personal communication, 2000). iscA, sufA, erpA and nfuA are paralogs, but GntY has an additional thioredoxin-like C-terminal domain. [More information is available at EcoGene: EG12935]. NfuA is an iron-sulfur protein which is able to transfer its [4Fe-4S] iron-sulfur cluster to apo-aconitase in vitro, thus identifying it as an iron-sulfur cluster scaffold protein . [More information is available at EcoCyc: G7748].
