Imidazole glycerol phosphate synthase (HisF) has been proposed to be the product of duplication of a gene encoding a (β/α)4-half barrel followed by fusion to encode the complete (β/α)8-barrel. In support of this evolutionary scenario, the N- and C-terminal (β/α)4-half barrels of HisF* have been separately expressed and purified. Each assumes a stable, soluble homodimeric structure, but neither is catalytically active; when expressed together, a functional heterodimer is formed.

Notes
NOTE: A typographical error has been corrected in the web version of the News & Views article by John A. Gerlt and Patricia C. Babbitt. The sentence in the first paragraph, "In support of this evolutionary scenario...4-half barrels of TrpF have been separately expressed and purified" has had TrpF changed to HisF. We apologize for any confusion these errors may have caused. The most current version of the article is available in the PDF format.
