Structure modeling of AfeI. (A) LasI and AfeI amino acid sequence alignment used for homology modeling. Boldface type indicates the most conserved region in the two proteins. Identical residues are indicated by asterisks, and similar residues are indicated by colons. A residue involved in oxo substitution (47) is indicated by a gray box. (B) AfeI modeled structure (right) based on LasI solved structure (left).
