The amino acid sequence of plastocyanin from Vicia faba L. (broad bean).
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 pe...
متن کاملThe Amino Acid Sequence of Chlorella fusca Plastocyanin
The sequences proposed in Fig. 1 for the Ps. aerirgirioJa and Ps. strrtzeri proteins have been confirmed by the isolation and characterization of the expected peptides from tryptic digests of the haeni-free proteins. From each of these two proteins a second tryptic peptide was isolated that contained two residues of cysteine and a residue of histidine. The amino acid composition was such that t...
متن کاملStudies of the Amino Acid Sequence of Plastocyanin from Rumex obtusifolius (Broad-Leaved Dock)
Plastocyanins are low-molecular-weight cuproproteins, which occur in the chloroplasts of plants and algae. The exact biological function of the protein remains uncertain, but is probably associated with photosynthetic electron transport (Gregory, 1971). The small size and blue colour of the protein simplify the purification of plastocyanin, and studies with a number of species have been reporte...
متن کاملl-Ornithine:2-Oxoacid Aminotransferase from Squash (Cucurbita pepo, L.) Cotyledons: Purification and Properties.
ORNITHINE: 2-oxoacid aminotransferase (EC 2.6.1.13) has been purified over 400-fold with a total recovery of 14% from acetone powders of cotyledons of germinating squash (Cucurbita pepo, L.) seedlings. The pH optimum of the transamination between l-ornithine and alpha-ketoglutarate is 8 and the Michaelis constants are 4.7 mm and 6.3 mm, respectively. The enzyme has a molecular weight of 48,000 ...
متن کاملThe amino acid sequence of plastocyanin from French bean (Phaseolus vulgaris).
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-bea...
