Titration of HbrL by exogenous addition of hemin. Affinity-purified HbrL-H6 (6.4 μM) was titrated by the addition of hemin (64 μM in DMSO) in 0.2 mol equivalents. Spectra were collected for HbrL-H6 and a control sample of lysozyme (6.4 μM); data presented are the difference spectra (HbrL minus lysozyme).
