Lineage
Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as
ECK4064; yjcI
Summary
SignalP strongly predicts a signal of 32 aa (34 aa if a GTG start at -2 is used), as previously noted (Clarke, 2004), but N-terminal sequencing found a cleavage after 25 residues (Clarke, 2007). [More information is available at EcoGene: EG11945]. The nrfB gene encodes a cytochrome C that is believed to be the direct electron donor for cytochrome C552 in the formate-dependent reduction of nitrite to ammonia. [More information is available at EcoCyc: EG11945].
