Identificação de domínios em β-glicosidases GH1 através da análise de sua estabilidade

Autor: Vitor Medeiros Almeida

Publikováno v: Biblioteca Digital de Teses e Dissertações da USPUniversidade de São PauloUSP.

Introdução e objetivos: β-glicosidases da família GH1 das glicosil-hidrolases possuem um dobramento do tipo barril (β/α)8. Propõe-se que proteínas com este dobramento, que usualmente classificam-se como tendo um único domínio, na verdade s�

The SARS-CoV-2 pandemic has already killed more than one million people worldwide. To gain entry, the virus uses its Spike protein to bind to host hACE-2 receptors on the host cell surface and mediate fusion between viral and cell membranes. As initi

Bacterial glycoside hydrolase 1 (GH1) enzymes with 6-phospho-β-galactosidase and 6-phospho-β-glucosidase activities have the important task of releasing phosphorylated and nonphosphorylated monosaccharides into the cytoplasm. Curiously, dual 6-phos

In this work, we investigated how activity and oligomeric state are related in a purified GH1 β‐glucosidase from Spodoptera frugiperda (Sfβgly). Gel filtration chromatography coupled to a multiple angle light scattering detector allowed separatio

Centralities determined from Residue Interaction Networks (RIN) in proteins have been used to predict aspects of their structure and dynamics. Here, we correlate the Eigenvector Centrality (Ec) with the rate constant for thermal denaturation (kden) o

The marine bacteria Saccharophagus degradans (also known as Microbulbifer degradans), are rod-shaped and gram-negative motile γ-proteobacteria, capable of both degrading a variety of complex polysaccharides and fermenting monosaccharides into ethano

PLoS ONE, Vol 13, Iss 1, p e0191282 (2018)

Proteins that fold as (β/α)8 barrels are thought to have evolved from half-barrels that underwent duplication and fusion events. The evidence is particularly clear for small barrels, which have almost identical halves. Additionally, computational c

The optimum temperature is commonly determined in enzyme characterization. A search in the PubMed database for "optimum temperature" and "enzymes" yielded more than 1,700 manuscripts reporting this parameter over the last five years. Here, we show th
