Conserved Hinge Motif Modulates Conformational Mobility of a Heme Trafficking Protein from Fusobacterium nucleatum

Fusobacterium nucleatum encodes HmuF, which has been shown in vitro to bind tightly to heme, traffic the cofactor to anaerobilin synthase, and catalyze the four-electron reduction of anaerobilin. The structure of the heme-bound HmuF paralog, FldH, reveals an α-helical cap appended to the flavodoxin domain. Molecular...
