Notes

[back to top]

Verified Tat substrate: FhuD has a predicted Tat-only (Class I) 30 aa signal peptide (Tullman-Ercek, 2007). The N-terminal sequence in Rohrback (1995), cited in Swiss-Prot, does not verify this putative SPI cleavage; it is the product of an enterokinase cleavage of a cloning construct. Rohrback (1995) demonstrated proper folding of FhuD in the cytoplasm prior to export, consistent with FhuD needing the Tat pathway, which exports folded proteins.^[4]
