Function

Part of the ATP-binding cassette (ABC) transport system PsaABC involved in manganese import. Binds manganese with high affinity and specificity and delivers it to the membrane permease for translocation into the cytoplasm. Also acts as an adhesin which is involved on adherence to extracellular matrix.

Biological Context

Subcellular Location: Cell membrane (Lipid-anchor)

Product Specifications
