Sensitivity improvement in 2D and 3D HCCH spectroscopy using heteronuclear cross-polarization
(Kluwer Academic Publishers; ESCOM Science Publishers B.V. ; Springer Science+Business Media, 1993-07)
A new method, which employs a sequence of heteronuclear-homonuclear-heteronuclear Hartmann-Hahn (HEHOHEHAHA) cross-polarization steps for obtaining through-bond H-C-C-H correlations in larger proteins (M r > 15 kDa), is ...
Line narrowing in spectra of proteins dissolved in a dilute liquid crystalline phase by band-selective adiabatic decoupling: Application to 1HN-15N residual dipolar coupling measurements
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-12)
Residual heteronuclear dipolar couplings obtained from partially oriented protein samples can provide unique NMR constraints for protein structure determination. However, partial orientation of protein samples also causes ...
Protein Kinase Inhibitors Block Neurite Outgrowth from Explants of Goldfish Retina
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-10)
A role for protein phosphorylation in the process of neurite outgrowth has been inferred from many studies of the effects of protein kinase inhibitors and activators on cultured neurotumor cells and primary neuronal cells ...
Isolation and expression of the Drosophila drosulfakinin neural peptide gene product, DSK-I
(Elsevier, 1992-08)
The Drosophila drosulfakinin (dsk) gene encodes the cholecystokinin homologues drosulfakinin-I (DSK-I) and drosulfakinin-II (DSK-II). The naturally occurring DSKI peptide was isolated from an extract of adult flies and its ...
Lack of correspondence between the room-temperature phosphorescence decay-components and Trp residues in a series of Trp-->Cys or Trp-->Phemutants of human carbonic anhydrase II
(Elsevier, 1994-10-17)
The room temperature phosphorescence of native human carbonic anhydrase (CA), and several mutants of this enzyme has been investigated. In these mutants the seven tryptophan residues in the native protein have sequentially ...
A comparative study of succinate-supported respiration and ATP/ADP translocation in liver mitochondria from adult and old rats
(Elsevier, 1991-06-14)
This study was undertaken to compare the rates of succinate-supported hepatic mitochondrial respiration between 12 months (adult) and 29 months (old) male Fischer 344 rats. Experiments were also performed to determine the ...
Crystallization and preliminary X-ray diffraction studies of the cobalamin-binding domain of methionine synthase from Escherichia coli
(Elsevier, 1992-05-20)
Crystals of a cobalamin-binding domain (Mr = 28,000) have been grown in polyethylene glycol 6000 at pH 7.5, starting from solutions of intact (Mr = 133,000) cobalamin-dependent methionine synthase. The crystals are ...
Localization of the corticotropin-releasing hormone receptor gene on mouse Chromosome 11
(Springer-Verlag, 1995-01)
Monoclonal antibodies that recognize the trisaccharide epitope Galα1-3Galβ1-4GlcNAc present on Ehrlich tumor cell membrane glycoproteins
(Springer-Verlag, 1993-08)
Monoclonal antibodies were prepared against the trisaccharide Galα1-3Galβ1-4GlcNAc, a sequence which occurs on the surface of Ehrlich ascites tumor cells as well as in thyroglobulin, laminin and a variety of other proteins. ...
[alpha]-(2 --> 3)- and [alpha]-(2 --> 6)-Sialyltransferase activities present in three variants of Ehrlich tumor cells: identification of the products derived from N-acetyllactosamine and [beta]--Gal-(1 --> 3)-[alpha] GalNAc-(1 --> O)-Bn
(Elsevier, 1994-11-01)
We compared several sialyltransferase activities related to synthesis of O-linked and N-linked sialylglycoproteins in Ehrlich ascites tumor cells that grow normally in murine ascites, but are not adherent nor grow in tissue ...
