Structural study of crystalline auromomycin. Preliminary X-ray diffraction study of auromomycin and macromomycin

Auromomycin and macromomycin from the organism Streptomyces macromomyceticus have been crystallized. The X-ray diffraction pattern of crystals of each molecule is consistent with space group P2(1)2(1)2 with cell parameters a = 46.45 A, b = 54.34 A and c = 42.03 A for auromomycin, and a = 46.45 A, b = 54.52 A and c = 41.54 A for macromomycin. Diffraction analysis of auromomycin is in progress.
