A protein superfamily, within which the sequences are recognizably related, usually encompasses all structures that diverged less than 400 million years ago and that changed mainly by point mutation. Many superfamilies extend throughout all eukaryotes or throughout a major division of bacteria, while the proteins of some superfamilies occur in all living organisms. All proteins may belong to fewer than 000 distinct superfamilies. To illustrate the new understanding which emerges from such an… Expand

Differentiation of Fraction 1 protein in relation to age and distribution of Angiosperm groups
TLDR
Electrofocusing F-1-protein resolves the large subunit polypeptides coded by extranuclear DNA and the small subunitPolypeptide coded by nuclear DNA and infer that species ofNicotiana and Gossypium have arrived in Australia via former land connections between S. America, Antarctica, and Australia. Expand
Origins of immunoglobulin heavy chain domains
TLDR
It is concluded that all of the sequenced heavy chains share a common ancestor consisting of four domains and that the two shorter heavy chains, alpha and gamma, have independently lost most of the second domain. Expand
Functional Proteins from Short Peptides: Dayhoff's Hypothesis Turns 50.
TLDR
Margaret Dayhoff's 1966 hypothesis on the origin of proteins is now an accepted model for the emergence of large, globular, functional proteins from short, simple peptides. Expand
Protein Engineering of Avidin by Rational Design and DNA Family Shuffling
Avidins represent an interesting group of proteins showing high structural similarity and ligand-binding properties but low similarity in primary structure. In this study, we show that it is possibleExpand
The case for a polyphyletic origin of mitochondria: Morphological and molecular comparisons
TLDR
It is proposed that the difference in cristal morphology is the result of separate origins of the mitochondria from endosymbionts related to the Rhodospirillaceae but differing in the morphology of their internal membranes. Expand
Superfamily classification in PIR-International Protein Sequence Database.
Publisher Summary This chapter discusses the superfamily classification in the Protein Information Resource (PIR)-International protein sequence database and the development of the model of theExpand
Directed evolution studies with combinatorial libraries of T4 lysozyme mutants
TLDR
The strong selective pressure uncovered an unexpected solution to the biochemical blocks, a frequently observed phenomenon in selection experiments, thus defining the limits of evolved enzymatic activity detectable in these selections. Expand
The Evolution of Human Cells in Terms of Protein Innovation
TLDR
It is concluded that exaptation of existing domain architectures into new contexts is the dominant source of cell-type–specific domain architectures. Expand
DeepProteomics: Protein family classification using Shallow and Deep Networks
TLDR
This work has collected the data from Swiss-Prot containing 40433 proteins which is grouped into 30 families and passes it to recurrent neural network, long short term memory, LSTM and gated recurrent unit (GRU) model and could achieve maximum of around 78% accuracy for the classification of protein families. Expand
Distributed Representations for Biological Sequence Analysis
TLDR
A new method is presented, called seq2vec, to represent a complete biological sequence in an Euclidean space, which has the potential to capture the contextual information of the original sequence necessary for sequence comparison tasks. Expand

The Amino-acid Sequence of Cytochrome c from Euglena gracilis
TLDR
It is shown that relating sequence data to the tertiary structure can generate hypotheses about functional regions that are evolutionarily conserved and this is an aspect of the current selectionist versus neutralist argument. Expand
Techniques for determining protein sequence evolution applied to primates
TLDR
Primate phylogeny from sequences of fibrinopeptides, carbonic anhydrase, and the hemoglobin beta, delta and alpha chains is elucidated, indicating that the early Pongidae had diverged into two lines before the divergence of an ancestor for the human line alone. Expand
Eukaryote evolution: A view based on cytochromec sequence data
TLDR
A phylogeny for these data is made by reconstructing probable ancestral sequences which generate the present descendants through a minimum number of mutations, and finds an early differentiation between prokaryote and eukaryote stocks. Expand
The amino acid sequence of cytochrome c from Helix aspersa Müller (garden snail).
TLDR
Comparison with amino acid sequences of cytochromes c from other sources indicates that the point of divergence of the molluscs and the vertebrates in evolutionary time was 720 million years ago. Expand
Cytochrome c2 of Rhodospirillum rubrum. II. Complete amino acid sequence and phylogenetic relationships.
TLDR
Internal homology in cytochrome c2 of R. rubrum is demonstrated for about 83% of the molecule, suggesting evolution of this protein from a small, repeating peptide unit. Expand
THE COVALENT STRUCTURE OF AN ENTIRE γG IMMUNOGLOBULIN MOLECULE
TLDR
The complete amino acid sequence of a human γG1 immunoglobulin (Eu) has been determined and the arrangement of all of the disulfide bonds has been established, and these data support the hypothesis that Immunoglobulins evolved by gene duplication after early divergence of V genes, which specified antigen-binding functions, and C genes, who specified other functions of antibody molecules.

TLDR
Two eukaryotic cytochrome c components, ca and cb, were purified from the thermophilic fungus Humicola lanuginosa and appear to differ only in the degree of methylation of lysyl amino groups. Expand

C-type cytochromes of Desulfovibrio vulgaris. The primary structure of cytochrome c 553.
TLDR
Comparison of the sequence of cyTochrome c553 of Desulfovibrio vulgaris with that of cytochrome c3 of the same organism revealed no homology, however, some similarities with Pseudomonas cy tochrome c551 were found. Expand
New concepts of kingdoms of organisms
TLDR
My purpose in this article is to discuss the merits of two classifications which depart from the traditional two kingdoms, the systems of Copeland (1-3) and Whittaker (4, 5). Expand
