The small subunit of ribonucleotide reductase from Escherichia coli has been crystallized in two new crystal forms. The form most suitable for X-ray analysis belongs to the orthorhombic space group P2(1)2(1)2(1). It has the cell dimensions 74.3 A, 85.5 A, 115.7 A and diffracts to about 2.1 A resolution. The asymmetric unit most probably contains one dimer. Absorption spectra of single crystals confirm that the crystals contain a binuclear iron center. Crystals of the iron-depleted apoenzyme have also been obtained.

D004926 Escherichia coli A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli

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).
