The X-ray crystal structure of the complex of the extracellular domain of the human 55 kd tumor necrosis factor (TNF) receptor with human TNF beta has been determined at 2.85 A resolution. The complex has three receptor molecules bound symmetrically to one TNF beta trimer. The receptor fragment, a very elongated end to end assembly of four similar folding(More)
The complete amino acid sequence of cytosolic adenylate kinase (MgATP + AMP----MgADP + ADP) from baker's yeast has been determined. Tryptic and clostripaic cleavage of the protein yielded 27 and 10 fragments, respectively. They were sequenced with either a solid-phase sequencer or a gas-phase sequencer. Alignment of the clostripaic fragments was deduced(More)
Malignant myelosclerosis or acute myelofibrosis is a rare acute myeloproliferative disorder characterized by pancytopenia, myeloblastosis and marrow fibrosis. We describe two patients who developed malignant myelosclerosis after receiving cytotoxic chemotherapy, one for Hodgkin's disease, and the other for membranous nephritis. In view of the known(More)
The syntheses and analyses of GSSG analogues with modified ionizable groups are described. Using the mixed anhydride method, three symmetrical and three asymmetrical peptide analogues were obtained in moderate overall yields. The products were analyzed by HPLC, 1H-NMR, thin-layer electrophoresis, and amino acid analysis. They were used to study(More)
A complex of tumour necrosis factor-beta with the soluble extracellular domain of the human 55 kDa TNF receptor has been crystallized. Crystals of the complex were grown using polyethylene glycol 4000 as the precipitating agent in the presence of beta-octyl glucoside. The receptor-ligand complex crystallizes in a cubic space group and diffracts to 2.85 A.
Six analogues of glutathione disulfide were synthesized. All of them involved the abolishment of charges, either by amidation of carboxylates or by removal of amino groups. Four of these analogues could be bound to crystalline oxidized glutathione reductase, and their binding modes could be established by X-ray analyses at 2.4-A resolution. All six(More)
