The amino acid sequence of plastocyanin from potato was determined. It consists of a single polypeptide chain of 99 residues, of molecular weight 10332. The sequence was determined by using a Beckman 890c sequencer and by dansyl–Edman analysis of peptides derived from purified CNBr fragments. The sequence shows considerable similarity with that of Chlorella fusca, and also with the C-terminal region of bacterial azurins.

The preparation and purification of tryptic peptides from aminoethylated Dip-elastase and [14C]carboxymethylated Dip-elastase, and of peptic peptides from native elastase is described. A summary of the results of chemical studies used to elucidate the amino acid sequence of these peptides is presented. Full details are given in a supplementary paper that has been deposited as Supplementary Publication SUP 50016 at the National Lending Library for Science and Technology, Boston Spa, Yorks. LS23 7BQ, U.K., from whom copies can be obtained on the terms indicated in Biochem. J. (1973), 131, 1–20. These results, together with those from previously published papers, are used to establish the complete amino acid sequence of elastase, which is a single polypeptide chain of 240 residues, molecular weight 25900, containing four disulphide bridges.

The amino acid sequence of the ferredoxin of Triticum aestivum (wheat) was determined by using a Beckman 890C sequencer in combination with the dansyl–phenylisothiocyanate method to characterize peptides obtained by tryptic, chymotryptic and thermolytic digestion of CNBr-cleavage fragments. The molecule consists of a single polypeptide chain of 97 residues and has an unblocked N-terminus. It shows considerable similarity to other plant-type ferredoxins.

The amino acid sequence of cytochrome c-553, an electron carrier in the photosynthetic apparatus of the unicellular alga Monochrysis lutheri, has been determined. The protein consists of a single polypeptide chain of 83 amino acid residues. The sequence shows homology with mitochondrial cytochrome c at each end of the chain. The N-terminal glycine is not acetylated and corresponds to position 1 of mammalian cytochrome c when the cysteine residues of the two proteins are aligned.

The amino acid sequence of plastocyanin from broad bean was determined. It consists of a single polypeptide chain of 99 residues. The sequence was determined by using a Beckman 890C sequencer and by dansyl–phenyl isothiocyanate analysis of peptides obtained by the enzymic cleavage of purified cyanogen bromide fragments. Some parts of the sequence depend on the results of Edman degradation of peptides for which amino acid analyses were not obtained. The evidence for one overlap is not strong.

The amino acid sequence of plastocyanin from the prokaryotic blue-green alga Anabaena variabilis was determined. The protein consists of a single polypeptide chain of 105 residues. The amino acid sequence of the plastocyanin was compared with that of the eukaryotic green alga Chlorella fusca and with those of higher-plant plastocyanins. The considerable similarity between the prokaryotic and eukaryotic plastocyanins is discussed. Detailed evidence for the sequence of the protein has been deposited as Supplementary Publication SUP 50051 (13 pages) at the British Library (Lending Division), Boston Spa, Wetherby, W.

The amino acid sequence of the plastocyanin from the green alga Chlorella fusca was determined. The protein consists of a single polypeptide chain of 98 residues, and was determined by characterization of chymotryptic and thermolysin peptides. The amino acid sequence shows considerable similarity to that of higher plant plastocyanins. The protein contains a single cysteine, and the sequence in the vicinity of this residue is similar to that around the cysteine residue of bacterial azurins. The plastocyanin contains some uncharacterized carbohydrate. Detailed evidence for the sequence of the protein has been deposited as Supplementary Publication SUP 50 036 (17pp., 1 microfiche) at the British Library (Lending Division) (formerly the National Lending Library for Science and Technology), Boston Spa, Yorks.

The amino acid sequence of the ferredoxin of Brassica napus was determined by using a Beckman 890C sequencer in combination with the characterization of peptides obtained by tryptic and chymotryptic digestion of the protein; some peptides were subdigested with thermolysin. The molecule consists of a single polypeptide chain of 96 amino acid residues and has an unblocked N-terminus. The primary structure shows considerable similarity with other plant-type ferredoxins.

The amino acid sequence of the penicillinase (penicillin amido-β-lactamhydrolase, EC 3.5.2.6) from Staphylococcus aureus strain PC1 was determined. The protein consists of a single polypeptide chain of 257 residues, and the sequence was determined by characterization of tryptic, chymotryptic, peptic and CNBr peptides, with some additional evidence from thermolysin and S. aureus proteinase peptides. A mistake in the preliminary report of the sequence is corrected; residues 113-116 are now thought to be -Lys-Lys-Val-Lys- rather than -Lys-Val-Lys-Lys-. Detailed evidence for the amino acid sequence has been deposited as Supplementary Publication SUP 50056 (91 pages) at the British Library (Lending Division), Boston Spa, Wetherby, West Yorkshire LS23 7BQ, U.K., from whom copies may be obtained on the terms given in Biochem.

The amino acid sequence of spinach (Spinacia oleracea L.) plastocyanin was determined. It consists of a single polypeptide chain of 99 residues and has a sequence molecular weight of 10415. The sequence was determined by using a Beckman 890C automatic sequencer and by the dansyl--phenyl isothiocyanate analysis of peptides obtained by the enzymic digestion of purified CNBr fragments. Overlap through the two methionine residues was not shown. Sedimentation equilibrium in the ultracentrifuge gave a molecular weight for spinach plastocyanin of about 9000, in contrast with the value of 21000 reported previously by Katoh et al. (1962).
