- Biología evolutiva
Sus antecedentes:
- Los pliegues de las proteínas están definidos por elementos estructurales secundarios y están interconectados.
- Los motivos de secuencia y estructura destacan las relaciones evolutivas en las estructuras de las proteínas.
- Comprender la evolución del pliegue de las proteínas requiere analizar los patrones de divergencia.
Objetivo del estudio:
- Para analizar la divergencia estructural en los pliegues de proteínas que contienen el motivo beta-martillo.
- Investigar las relaciones evolutivas entre las superfamilias utilizando motivos de secuencia y estructura.
- Discutir la divergencia de pliegues y la degeneración de motivos en el contexto de la evolución de las proteínas.
Principales métodos:
- Análisis basado en secuencias de motivos de proteínas.
- Análisis basado en la estructura de los motivos de proteínas.
- Análisis comparativo de las superfamilias Beta Barrel, Distorted Sandwich y Alpha-Beta Complex.
Principales resultados:

Protein Folding
8.6K
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.

Conservation of Protein Domains Over Different Proteins
11.3K
Protein domains are small structurally independent units that are part of a single amino acid chain. Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Protein and Protein Structure
81.3K
Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective. They may serve in transport, storage, or membranes; or they may be toxins or enzymes. Their structures, like their functions, vary greatly. They are all, however, amino acid polymers arranged in a linear sequence.

Molecular Chaperones and Protein Folding
18.4K
The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.

Amyloid Fibrils
9.9K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...
