<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Involved in the uptake of iron in complex with ferrichrome, a hydroxamate-type siderophore. Binds and transports ferrichrome-iron across the outer membrane (PubMed:1089064, PubMed:2066336).

In addition to its role in ferrichrome-iron transport, transports the antibiotic albomycin, which is a structural analog of ferrichrome, and acts as a receptor for colicin M, microcin J25 and bacteriophages T1, T5, phi80 and UC-1 (PubMed:1089064, PubMed:353030, PubMed:2066336, PubMed:8617231).

The energy source, which is required for all FhuA functions except infection by phage T5, is provided by the inner membrane TonB system (PubMed:353030, PubMed:9353297, PubMed:12427941).

Has two distinct conformations in the presence and absence of ferrichrome. The globular N-terminal domain acts a plug that closes the channel formed by the beta-barrel. Binding of ferrichrome at the cell surface induces a conformational change in FhuA, but does not open the channel. Structural changes are propagated and amplified across the plug, and may facilitate binding of FhuA to TonB (PubMed:9865695, PubMed:9353297). TonB binding promotes conformational changes in outer surface-exposed loops of FhuA (PubMed:18653801). Phage T5 is a TonB-independent ligand, and its binding to FhuA results in the formation of high conductance ion channels (PubMed:8617231, PubMed:9353297).4 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
