Abstract
Crystals of the molybdo-/iron-sulfur protein pyrogallol:phloroglucinol hydroxyltransferase (transhydroxylase; EC 1.97.1.2) from Pelobacter acidigallici were grown by vapour diffusion in an N-2/H-2 atmosphere using polyethylene glycol as a precipitant. In this microorganism, transhydroxylase converts pyrogallol to phloroglucinol in a unique reaction without oxygen transfer from water. Growth of crystals suitable for X-ray analysis was strongly dependent on the presence of dithionite as a reducing agent. The crystals belonged to space group P1 and MAD data were collected on the iron K edge to resolutions higher than 2.5 Angstrom.
