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 plastocyanin from French bean (Phaseolus vulgaris) was determined. The protein consists of a single polypeptide chain of 99 residues, and the sequence was determined by characterization of CNBr, tryptic, chymotryptic and thermolysin peptides. When the sequence is compared with that from the plastocyanin of the unicellular green alga Chlorella fusca, the French-bean protein shows the deletion of the N-terminal residue, a two residue insertion and 53 identical residues.

The amino acid sequence of plastocyanin from marrow was determined. It consists of a single polypeptide chain of mol.wt. 10284 containing 99 amino acid residues. The sequence was determined by using a Beckman 890C automatic sequencer and by dansyl–phenyl isothiocyanate analysis of peptides obtained by the enzymic digestion of purified CNBr fragments. The sequence is in good agreement with the amino acid composition, except that fewer residues of glutamic acid were found in the sequence than were suggested by the composition. Evidence for histidine-37 was weaker than for the rest of the sequence. A ‘tree’ of phylogenetic affinities was constructed by using several higher-plant plastocyanin sequences.

The amino acid sequence of locust cytochrome c was determined, although the overlap between chymotryptic and tryptic peptides at residues tyrosine-97 and leucine-98 was not observed, owing to an anomalous tryptic break duplicating the chymotryptic digestion. The molecule consists of a single polypeptide chain of 107 residues, homologous with other mitochondrial cytochromes c. In common with other known insect cytochromes c, it possesses a non-acetylated, four-residue tail at the N-terminus relative to glycine-1 of the standard alignment. A molecular phylogeny for 17 species was constructed relating the cytochrome c molecules of Schistocerca gregaria and other invertebrates with those of representative taxonomic groups.

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-.

An amino acid sequence is proposed for the cytochrome c′ from the photosynthetic purple sulphur bacterium Chromatium vinosum strain D. It is single polypeptide chain of 131 residues, with haem-attachment cysteine residues at positions 121 and 124. The results discredit an earlier report [Dus, Bartsch & Kamen (1962) J. Biol. Chem 237, 3083–3093] of a di-haem peptide sequence from this protein. The sequence belongs to the same class as the published Alcal!igenes and Rhodospirillum rubrum cytochrome c′ squences, but the resemblance is not close.

An amino acid sequence is proposed for the cytochrome c4 from the bacterium Azotobacter vinelandii strain OP. It is a single polypeptide chain of 190 residues, with two sets of haem-attachment cysteine residues at positions 14/17 and 119/122. Proteins with similar sequences are also present in denitrifying pseudomonads. There is similarity in sequence between the two halves of the cytochrome c4 molecule, and each half also shows similarity to the sequences of certain monohaem cytochromes c isolated from organisms that are not obviously closely related to A. vinelandii.

The amino acid sequence of the cytochrome c-555 from the obligate methanotroph Methylococcus capsulatus strain Bath (N.C.I.B. 11132) was determined. It is a single polypeptide chain of 96 residues, binding a haem group through the cysteine residues at positions 19 and 22, and the only methionine residue is a position 59. The sequence does not closely resemble that of any other cytochrome c that has yet been characterized.

Cytochrome f was isolated from the brown alga Alaria esculenta and the amino acid sequence was determined. The native haemoprotein has a molecular weight of 9800 and consists of a single polypeptide chain of 86 amino acid residues with a haem group bonded to cysteine residues at positions 14 and 17. The N-terminus is not acetylated and no methylated lysines were found. Sequences of three other algal cytochromes f were compared with that of Alaria and 22 out of 92 positions were common to the four sequences. One-half of these conserved sites occur between positions 49 and 63. Detailed evidence for the amino acid sequence of Alaria cytochrome has been deposited as Supplementary Publication SUP 50048 (6 pages) at the British Library (Lending Division), Boston Spa, Wetherby, West Yorkshire LS23 7BQ, U.K., from whom copies can be obtained on the terms indicated in Biochem.
