Cleavage of cytochrome c with cyanogen bromide

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1970
Abstract Heme peptides and nonheme peptides suitable for use in binding studies have been prepared by cleavage of horse cytochrome c with cyanogen bromide. These derivatives include a heme peptide of 65 residues and a peptide of 39 residues obtained by division of the protein at the bond following methionine residue 65.

Cyanogen bromide fragments of human serum transferrin

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1973
Abstract Human serum transferrin was fragmented by a combination of methods involving cyanogen bromide, acylation, and reduction-alkylation. Six fragments were isolated in a homogeneous form, and their molecular weights were 26 000; 16 000; 15 000; 9000; 6000; and 4000 (the N-terminal fragment of transferrin), thus accounting for the molecular weight

Cyanogen bromide treatment of methionine-containing compounds

Biochemistry, 1977
The preparation of a series of X-Met-Gly-OEt and X-Met-Phe-OMe and their treatment with CNBr in either 70% or 97-100% formic acid at 25 degrees C are described where X is methanesulfonyl (mesyl), p-nitrobenzyloxycarbonyl, phthaloyl, trifluoroacetyl, acetyl, formyl, or tert-butyloxycarbonyl.

Cyanogen bromide splitting of human immunoglobulin M

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1973
Human Waldenstrdm IgM (kappa) (Dau), its polypeptide chains and its F(c)5 micro and Fab micro fragments were split by cyanogen bromide (CNBr). The fragments formed by CNBr were fractionated by gel filtration, ion exchange chromatography and paper electrophoresis.

The force fields of cyanogen halides. III. Cyanogen bromide and cyanogen iodine

Spectrochimica Acta Part A: Molecular Spectroscopy, 1978
Abstract Following work determining the force fields of FCN and ClCN a related treatment for BrCN and ICN leads to the force fields indicated in Table 1 and giving the agreement with experiment shown by Tables 3, 4 and 5 for BrCN and Tables 7 and 8 for ICN. Table 6 gives the agreement of B 0 values for all isotopic molecules with r e values for

Cyanogen Bromide Fragments of Rabbit Skeletal Tropomyosin

Canadian Journal of Biochemistry, 1973
Previous studies have demonstrated that rabbit skeletal tropomyosin consists of two or more chemically non-identical but highly homologous polypeptide chains. Attempts by a variety of techniques to prepare pure tropomyosin chains in amounts adequate for chemical characterization have been unsuccessful to date. To provide more extensive information for

Threshold photoelectron spectroscopy of cyanogen bromide

Chemical Physics Letters, 2004
Abstract A high-resolution (2–15 meV) threshold photoelectron (TPE) spectroscopic study of BrCN was performed using synchrotron radiation and a penetrating-field electron spectrometer over the outer valence ionization region of the molecule. Significant differences were found between the TPE spectrum and the published high-resolution (∼6 meV) HeI ...

Fragmentation reactions promoted by cyanogen bromide

Canadian Journal of Chemistry, 1969
The fragmentation of α-4-dimethylamino-3-methyl-1,2-diphenylbutan-2-ol to cis H/Ph 3-methyl-1,2-diphenylprop-2-ene, normally induced by treating the corresponding 2-chloro derivative with a base, also results when the alcohol itself is treated with cyanogen bromide; related γ-hydroxy acyclic tertiary amines similarly undergo fragmentation in this ...
