Orientation of non-blue cupric complexes on DNA fibers.

Three different orientations of non-blue, type 2 cupric complexes on DNA fibers are obtained from EPR data. The cupric complex of bleomycin, CuBlm, binds as described previously (Shields, H., McGlumphy,C., and Hamrick, P., J., Jr. (1982) Biochim. Biophys. Acta 697, 113-120), except possibly with more restricted motion. The square plane of CuBlm makes an angle of about 65 degrees with the fiber ...

Optical mapping of protein-DNA complexes on chromatin fibers.

Immunofluorescence (IF) and Fluorescence in situ Hybridization (FISH) are conventional methods used to study the structure and organization of metaphase chromosomes and interphase nuclei. Using these techniques, the locations of whole chromosome territories, chromatin subdomains, and specific DNA sequences can be evaluated at kilobase or megabase resolution. Even higher resolution of the spatia...

Cupric ion complexes of histidine-containing peptides.

The binding of cupric or zinc ion by sperm whale metmyoglobin appears to involve imidazole groups of histidyl residues (4, 5) that occur well removed from the NH2 terminus (6). The binding of each cupric ion by metmyoglobin is accompanied on the average by the displacement of one or more protons beyond that that may be borne by the imidazole group, presumably from peptide amide nitrogen atoms (...

The Orientation of Dna within 80-angstrom Chromatin Fibers

Squashing salivary glands of Chironomus thummi larvae, Amblystoma tigrinum erythrocytes, or Spirostromum frequently results in stretched chromatin having highly oriented DNA as determined by polarized fluorescence microscopy of acridine orange-stained preparations. The examination of such material from C. thummi in the electron microscope indicates that the individual chromatin fibers have an a...
