Cytochrome c551 peroxidase is a periplasmic enzyme expressed in Pseudomonas aeruginosa at low oxygen tensions. The glycosylated enzyme has been purified to homogeneity and crystallized by vapour diffusion techniques using polyethylene glycol 2000 as the precipitant in the presence of isopropanol. The crystals belong to the trigonal space group P3(1)21 or P3(2)21 with unit cell dimensions of a = b = 113.8 A, c = 72.0 A. They are suitable for X-ray analysis and diffract to dmin = 2.5 A. There is one peroxidase molecule in the crystallographic asymmetric unit.

UI MeSH Term Description Entries
D011550 Pseudomonas aeruginosa A species of gram-negative, aerobic, rod-shaped bacteria commonly isolated from clinical specimens (wound, burn, and urinary tract infections). It is also found widely distributed in soil and water. P. aeruginosa is a major agent of nosocomial infection.

D014961 X-Ray Diffraction The scattering of x-rays by matter, especially crystals, with accompanying variation in intensity due to interference effects. Analysis of the crystal structure of materials is performed by passing x-rays through them and registering the diffraction image of the rays (CRYSTALLOGRAPHY, X-RAY).
