Ferric-binding protein: Difference between revisions

Revision as of 11:35, 27 July 2020

Function

The process of bacterial multiplication requires the acquisition of growth-essential nutrients including iron, from the host cell. Ferric-binding protein (FBP) transfers iron across the periplasmic space from human transferrin to pathogenic bacteria^[1].

Structural highlights

The in FBS includes with 2 tyrosine side chains (PDB code 3od7).^[2] Water molecule is shown as red sphere.

Ferric-binding protein complex with Fe+3 (orange) and phosphate ion (PDB code 3od7).
