Preliminary crystallographic studies of dimethylsulfoxide reductase from Rhodobacter capsulatus.
Dimethylsulfoxide reductase from the photosynthetic bacterium Rhodobacter capsulatus has been crystallized in two similar forms which are suitable for X-ray structure determination. Both crystals forms belong to space group P4(1)22 or P4(3)22, with cell dimensions a = b = 80.81, c = 229.75 A (type I crystals) or a = b = 89.30, c = 230.05 A (type II crystals) and one molecule in the asymmetric unit. Diffraction has been observed to at least 2.0 A in type I crystals and to 2.6 A in type II crystals. Dimethylsulfoxide reductase from Rhodobacter is the simplest molybdenum oxotransferase known and this makes it an ideal model to study the structure and function of this class of enzymes.
