Octaketide synthase (OKS) from Aloe arborescens is a plant‐specific type III polyketide synthase that produces SEK4 and SEK4b from eight molecules of malonyl‐CoA. Recombinant OKS expressed in Escherichia coli was crystallized by the hanging‐drop vapour‐diffusion method. The crystals belonged to space group I 422, with unit‐cell parameters a = b = 110.2, c = 281.4 Å, α = β = γ = 90.0°. Diffraction data were collected to 2.6 Å resolution using synchrotron radiation at BL24XU of SPring‐8.
