THE MOST CONSERVED NUCLEAR-ENCODED POLYPEPTIDE OF CYTOCHROME-C- OXIDASE IS THE PUTATIVE ZINC-BINDING SUBUNIT - PRIMARY STRUCTURE OF SUBUNIT-V FROM THE SLIME-MOLD DICTYOSTELIUM- DISCOIDEUM
No full textA full-length 515 base pairs cDNA for cytochrome c oxidase subunit V of D. discoideum was isolated from a lambda gt11 expression library. The encoded polypeptide, whose identity was confirmed by partial protein sequencing, is 119 amino acids long (Mr = 13,352) and does not contain a cleavable presequence. The protein, which is homologous to human subunit Vb and yeast subunit IV, exhibits the highest degree of sequence conservation found among nuclear-encoded subunits of cytochrome c oxidase from distantly related organisms. All the invariant residues are clustered in two regions of the C-terminus which include the putative amino acids involved in the coordination of the Zn ion tightly associated to eukaryotic oxidase

No full textCharacterization of a cDNA encoding subunit VI of cytochrome c oxidase from the slime mold Dictyostelium discoideum.
No full textThe primary structure of subunit VI of cytochrome c oxidase from the slime mold Dictyostelium discoideum has been determined by sequencing cDNA and N-terminus of the protein. The 92 amino acid residues long polypeptide (Mr = 10,535) shows homology with subunit IV of mammalian and subunit V of yeast cytochrome c oxidase. Though smaller and synthesized without a cleavable presequence, the slime mold oxidase subunit maintains the presence of a putative membrane spanning region

THE 2 OXYGEN-REGULATED SUBUNITS OF CYTOCHROME-C OXIDASE IN DICTYOSTELIUM-DISCOIDEUM DERIVE FROM A COMMON ANCESTOR
No full textThe two smallest polypeptide components of D. discoideum cytochrome c oxidase, whose alternative expression depends on oxygen concentration [Schiavo, G. and Bisson, R. (1989) J. Biol. Chem. 264, 7129-7134], have been partially sequenced. They show 45% homology and are isoforms of the same subunit, which must be encoded on two different genes
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
