Function

Neisseria acquires iron by extracting it from serum transferrin (TF) in its human host. Acts as a TF receptor and is required for TF utilization. Binds both apo- and holo-TF, via the TF C-terminus.

Biological Context

Subcellular Location: Cell outer membrane (Multi-pass membrane protein)

Product Specifications

Recombinant Neisseria meningitidis serogroup B Transferrin-binding protein 1 (tbp1), partial is a recombinant protein from Neisseria meningitidis serogroup B (strain MC58), expressed in E.coli, covering amino acids 22-300aa, with N-terminal 10xHis-tagged and C-terminal Myc-tagged tag, molecular weight 37.0kDa, purity Greater than 85% as determined by SDS-PAGE..
