Phenotypes of a mutant

• poor growth with the xenosiderophores arthrobactin or aerobactin as single source of iron [Pubmed|23220087]

The protein

Protein family

• Fe/B12 periplasmic-binding domain (according to Swiss-Prot)

Modification

• phosphorylation on (Ser-290 OR Thr-302) [Pubmed|17218307]

[SW|Localization]

• associated to the membrane (via [protein|34A7E22B4EF118EF5A76F8CC2DABBB023BC9A2E9|YfhA]-[protein|81494D4E7E52531802C3C0D0073739DA9375F5DF|YfiZ]) [Pubmed|10092453,18763711]
