Figure 3. Haemoglobin can pull down various HpuA homologues.
Coomassie-stained gel showing Hb, Hb:Hp and albumin control (BSA) beads pulling down KdHpuA (lanes 1–3), NgHpuA (lanes 4–6) and EcHpuA (lanes 7–9) proteins. Binding reactions were carried out in 500 ml solutions containing 3 μM HpuA. Input samples of all proteins used are shown in lanes 10–15.
