Expression, purification and crystallization of an indole prenyltransferase from Aspergillus fumigatus.

ABSTRACT: CdpNPT from Aspergillus fumigatus is a dimethylallyltryptophan synthase/indole prenyltransferase that catalyzes reverse prenylation at position N1 of tryptophan-containing cyclic dipeptides. Residues 38-440 of CdpNPT were expressed in Escherichia coli and crystallized using the sitting-drop vapour-diffusion and microseeding techniques. The crystals belonged to space group P2(1)2(1)2(1), with unit-cell parameters a = 84.4, b = 157.1, c = 161.8 Å, α = β = γ = 90.0°.
