Ribbon diagram of E. coli Gab. (A) Oligomeric architecture of the Gab tetramer. Monomers are colored yellow, blue, gold, and green. The N terminus is labeled N for each protomer. Large magenta spheres mark the Fe(II) ion in each protomer. Each active site is well separated and distinct. Oligomeric interactions are mediated primarily between α1–3 and α5–6 between respective protomers. (B) Protomer of the Gab protein. N- and C-terminal residues are denoted with an N and C, respectively. Secondary structural elements are denoted α1–7 and β1–16 corresponding to the sequence alignment presented in Fig. 3 ▶. Active site Fe(II) and residues His 160, Asp 162, His 292, and Arg 305 are labeled. Graphics prepared using SETOR (Evans 1993).

Structure-based sequence alignment for Gab with other non-haem iron oxygenases. Structure-based sequence alignment produced by PrISM (Yang and Honig 1999). 1JR7, 1drt, 1dcs, and 1bk0 represent PDB codes for E. coli Gab, clavaminate synthase 1 (CAS), deacetoxycephalosporin C synthase (DOACS), and isopenicillin N synthase (IPNS), respectively. Highlighted residues in alignment are color-coded blue (active site residues) and magenta if conserved across all family members, yellow if conserved between DOACS and IPNS, and orange if conserved between CAS and Gab. Sequence identities in the structure-based alignment revealed 15.6% identity between Gab and CAS, 10.3% identity between Gab and DOACS, 5.0% identity between Gab and IPNS; 18.3% sequence identity was found between DOACS and IPNS, 7.4% identity between DOACS and CAS, and 9.8% identity between CAS and IPNS. Secondary structural elements (above) and sequence numbering (below) are shown for E. coli Gab in the alignment.

(A) P097 is a three-layer α-β-α sandwich. β Strands are painted as cyan, α helices are painted as red, and loops are painted as gray. (B) P097 forms a tightly packed dimer. Large red spheres represent putative metal ions.

Multiple alignments of 16 sequences with at least 30% identity to P097 from the Swiss-Prot database revealed several conserved regions (A,B). (red) Completely conserved residues; (white) nonconserved residues. (A) The P097 monomer. Conserved residues at the dimer interface are revealed as a red patch on the righthand side of the molecule. (B) The surface of the P097 dimer. The two putative metal ions are represented by blue spheres and may indicate important ligand binding sites as indicated by the conserved residues around the putative metal binding site. Conserved residues at the dimer interface are completely buried.
