A. baumannii hemoglobin structural model and its comparison with flavohemoglobin, single domain and truncated globins. (A) AlphaFold 3 model structure for A. baumannii hemoglobin (green) showing the two domains and the relative position of the b-type heme. Highlight on the b-type heme and the conserved residues in its vicinity. (B-D) Structural superposition of AlphaFold 3 model structure for A. baumannii hemoglobin (green) with the Vitreoscilla stercoraria single domain globin (PDB1VHB, pink) (B); the E. coli flavohemoglobin (PDB1GVH, yellow) (C); and Mycobacterium tuberculosis truncated globin (PDB1IDR, gray) (D).
