Nickel-binding periplasmic protein: nikA

Gene

nikA

Protein

Nickel-binding protein NikA

Organism

Staphylococcus aureus (strain NCTC 8325)

Length

491 amino acids

Function

Part of the ABC transporter complex NikABCDE (Opp2) involved in nickel import. Binds nickel and transfers it to the membrane-bound permease. Required for full urease activity and plays a significant role in the virulence of S.aureus during urinary tract infection (UTI) (PubMed:20662775). May bind nickel via a nickel-chelator (PubMed:25611161).

Similarity

Belongs to the bacterial solute-binding protein 5 family.
