The amino-acid sequences of all expressed hemoglobins of the pig embryo are given: Hemo­globin Gower I (ζ2/ε2), Hemoblobin Gower II (α2/ε2), Hemoglobin Heide I (ζ2/ϑ2) and Hemo­globin Heide II (α0/ϑ2). The ζ-, ε- and ϑ-chains were obtained with chromatography on CM-cellulose from isolated hemoglobin components. The primary structure was established by sequencing the tryptic peptides in the sequenator: they where isolated using HPLC. The ζ-chains from pig and human differ in 23, the ε-chains in 20 positions. The embryonic globin-gene which express the ϑ-chains, is a new one in mammals, of ε-type and up to now it could only be found in pigs: the amino-acid sequence differ in only 4 positions from the ε-chains. Because no γ-chains (fetal Hb) are expressed the sequences of all hemoglobins (5 hemoglobin chains forming 5 different hemo­globins) of ontogeny in pig are now described.

Through the work of Magnusson and co-workers leading to the elucidation of the primary structure of prothrombin including the amino acid sequences around the two bonds split by factor Xa it has been possible to design a synthetic chromogenic peptide substrate. Bz-Ile-Glu-Gly-Arg-pNA, specifically intended for the determination of factor Xa. Furthermore, additional substrates have been synthezised with various alterations in the amino acid sequence. The activity of factor Xa and other serine proteases within the coagulation and fibrinolytic systems towards these substrates will be discussed with special regard to their possible use in coagulation studies.

The complete amino acid sequences of the hemoglobins from the adult European polecat (Mustela putorius) are presented. The erythrocytes contain two hemoglobin components and three globin chains (α I, α II and β). The primary structure of globin chains and of the tryptic peptides determined in liquid- and gas-phase sequantors. Comparing the sequences of the globin chains of the polecat with that of human Hb-A, 17 (23.9%) substitutions were recognized in the α I, 16 (22.5%) in the α II and 14 (20.4%) in the β chain. A high degree of homology observed with other representatives of the family Mustelidae.

The sequence of amino acids within the coat protein of the strain Holmes rib grass of tobacco mosaic virus (TMV) has been determined. In this communication the amino acid compositions of the coat protein and of all tryptic peptides are reported. Furthermore the experimental details are given for the elucidation of the amino acid sequences within the first three tryptic peptides, containing 61 amino acids.It has been found that the strain Holmes rib grass differs very extensively in the primary structure from the other TMV strains whose sequences are known. It differs from each of the other strains in more than 50% of the amino acid positions and it contains two amino acids less per protein subunit than the other TMV strains.

Experimental data for determining a) the amino acid sequences of eight tryptic peptides containing 95 amino acids and b) the order of the tryptic peptides are given. Combining the data of this and of a previous paper the complete amino acid sequence of the coat protein of the TMV strain Holmes rib grass (HRG) is established (Fig. 5). It is compared with three other TMV strains the sequences of which have been determined before (Fig. 6).Differences and similarities between the sequences of the four TMV strains are discussed. HRG has a deletion of two amino acids and it is the most distantly related of the four TMV strains. When the sequence of HRG is compared to that of any of the other strains it turns out that in each case more than 50% of the 156 positions contain different amino acids (Fig. 7).The number of positions with the same amino acid in all strains and mutants so far studied is 30 per cent. These positions are not randomly distributed but clustered mainly in two regions. This finding probably reflects the restriction of amino acid exchanges by the spatial structure of the viral rod.

Alpha chains of human haptoglobin have been prepared from whole haptoglobin of genetic type Hp 2–1 purified from the ascites fluid of a single patient. Amino acid sequence analysis has been carried out on these light chains which represent the products α1S and α2(F,S) of the single genes Hp1S and Hp2(F,S), and are, respectively, 83 and 142 residues in length. The data reported here concern the sequence analysis of two series of tryptic peptides, one obtained by unlimited cleavage of the chains by p-toluene sulfonamido-phenylethyl chloromethyl ketone - trypsin, and the second following limitation of trypsin cleavage to arginyl residues after modification of lysyl residues by trifluoracetylation. The major technique for sequence analysis of these peptides was a modification of the p-dimethylaminonaphthalene-sulfonyl-Edman (dansyl-Edman) procedure employing a new thin-layer chromatographic separation of the dansyl-amino acids. The sequences of these tryptic peptides in conjunction with those of the chymotryptic peptides allowed the unequivocal deduction of portions of the sequence, but the final overlaps were provided by fragments obtained by specific chemical cleavage of the chain at aspartyl residues. The amino acid sequences deduced have documented the occurrence of a partial gene duplication in the gene product α2(F,S) of the Hp2(F,S) gene.
