As part of a comparative study of egg yolk from different avian species, the major lipoprotein and its mixed apoproteins from the egg yolk of the chinese goose (Anser cygnoides) have been prepared. From the apoprotein mixture, two new proteins, of molecular weight approximately 10000 and 22000 according to gel electrophoresis in detergent, have been isolated by gel-filtration chromato-graphy in urea. The protein of lower molecular weight corresponds in amino acid sequence to apovitellenin I, a protein previously isolated from other avian species. As a comparison with other members of the same avian family (Anatidae), the amino acid sequence of apovitellenin I from the pekin duck (Anas platyrhynchos) was re-investigated and that of the muscovy duck (Cairina moschata) investigated. These were found to be identical to the sequence of goose's apovitellenin I. The second new protein is similar in composition, molecular weight, and solubility to apovitellenin II, a protein present in small amount in hen's egg yolk. A protein corresponding to apovitellenin II could not, however, be detected in the egg yolk of either species of duck.

<p>Protein folding is strictly related to the determination of the backbone dihedral angles and depends on the information contained in the amino acid sequence as well as on the hydrophobic effect. To date, the type of information embedded in the amino acid sequence has not yet been revealed. The present study deals with these problematics and aims to furnish a possible explanation of the information contained in the amino acid sequence, showing and reporting rules to calculate the backbone dihedral angles φ. The study is based on the development of mechanical forces once specific chemical interactions are established among the side chain of the residues in a polypeptide chain. It aims to furnish a theoretical approach to predict backbone dihedral angles which, in the future, may be applied to computational developments focused on the prediction of polypeptide structures.</p>

The complete amino acid sequence of yeast phosphoglycerate mutase comprising 241 residues has been determined. The sequence was deduced from the two cyanogen bromide fragments, and from the peptides derived from these fragments after digestion by a number of proteolytic enzymes. Determination of this sequence now allows a detailed interpretation of the existing high-resolution X-ray crystallographic structure. A comparison of the sequence reported here with the sequences of peptides from phosphoglycerate mutases from other species, and with the sequence of erythrocyte diphosphoglycerate mutase, indicates that these enzymes have a high degree of structural homology. Autolysis of phosphoglycerate mutase by yeast extracts leads to the complete loss of mutase activity, and the formation of electrophoretically distinguishable forms (R. Sasaki, E. Sugimoto & H. Chiba, Archs Biochem. Biophys. 115, 53-61 (1966)). It is apparent from the amino acid sequence that these changes are due to the loss of an 8─12 residue peptide from the C-terminus.
