Abstract

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 compmete (β/α)₈-barrel. In support of this evolutionary scenario, the N- and C-terminal (β/α)₄-half barrels of TrpF 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.
