A 42-kDa bovine protein that binds bovine angiogenin [angiogenin binding protein (AngBP)] has been identified as a dissociable cell-surface component of calf pulmonary artery endothelial cells and a transformed bovine endothelial cell line, GM7373. Binding of 125I-labeled bovine angiogenin (125I-Ang) to AngBP occurs with an apparent Kd approximately 5 x(More)
Homology analyses of the protein sequences of chicken liver and rat mammary gland fatty acid synthases [acyl-CoA:malonyl-CoA C-acyltransferase (decarboxylating, oxoacyl- and enoyl-reducing and thioester hydrolyzing), EC 2.3.1.85] and yeast fatty acid synthase [fatty-acyl-CoA synthase; acyl-CoA:malonyl-CoA C-acyltransferase (decarboxylating, oxoacyl- and(More)
The amino acid sequences associated with pyridoxal 5'-phosphate binding sites in chicken liver fatty acid synthase have been determined: a site whose modification causes selective inhibition of the enoyl reductase activity and a site (site I) that is not associated with enzymatic activity. The amino acid sequences of peptides obtained by trypsin hydrolysis(More)
The spatial relationships between the four reduced nicotinamide adenine dinucleotide phosphate (NADPH) binding sites on chicken liver fatty acid synthase were explored with electron paramagnetic resonance (EPR) and spin-labeled analogues of NADP+. The analogues were prepared by reaction of NADP+ with 2,2,5,5-tetramethyl-1-oxy-3-pyrroline-3-carboxylic acid,(More)
The amino acid sequences of three essential regions of chicken liver fatty acid synthase have been determined: that around 4'-phosphopantetheine ("carrier" site), the substrate "loading" site containing serine, and a "waiting" site for the growing fatty acid containing cysteine. The amino acid sequence of the 4'-phosphopantetheine region was determined for(More)
Angiogenin is a member of the ribonuclease superfamily that induces the formation of new blood vessels. It has been suggested that the surface loop of angiogenin defined by residues 59-71 plays a special role in angiogenic function (1); however, the mechanism of action is not clearly defined. To elucidate the role of the surface loop on the structure,(More)
