TL;DR: In this paper, a comparative genome analysis of C. subvermispora and P. chrysosporium was conducted to investigate the basis for selective ligninolysis.
Journal ArticleDOI
Cloning and sequencing of two Ceriporiopsis subvermispora bicupin oxalate oxidase allelic isoforms: Implications for the reaction specificity of oxalate oxidases and decarboxylases
Marta R. Escutia,Laura Bowater,Anne Edwards,Andrew R. Bottrill,Matthew R. Burrell,Rubén Polanco,Rafael Vicuña,Stephen Bornemann +7 more
TL;DR: It is shown that both fungal isoforms, one of which was heterologously expressed in Escherichia coli, are indeed oxalate oxidases that possess ≤0.2% oxalated decarboxylase activity and that the organism is capable of rapidly degrading exogenously supplied oxalates, the first bicupin oxalATE oxidases to have been described.
Journal ArticleDOI
Expression of genes encoding laccase and manganese-dependent peroxidase in the fungus Ceriporiopsis subvermispora is mediated by an ACE1-like copper-fist transcription factor.
José M. Alvarez,Paulo Canessa,Rodrigo A. Mancilla,Rubén Polanco,Paulina A. Santibáñez,Rafael Vicuña +5 more
TL;DR: Surprisingly, ACE1 factors from both basidiomycetes exhibit substantial differences, not only structurally but also in their ability to complement the aforementioned yeast strain.
Journal ArticleDOI
Study of the structure–bioactivity relationship of three new pyridine Schiff bases: synthesis, spectral characterization, DFT calculations and biological assays
Alexander Carreño,César Zúñiga,Dayán Páez-Hernández,Manuel Gacitúa,Rubén Polanco,Carolina Otero,Ramiro Arratia-Pérez,Juan A. Fuentes +7 more
TL;DR: In this article, three new pyridine Schiff bases were synthesized and characterized to explore their structure-bioactivity relationship as antifungal agents and provided data supporting a correlation between the structure and bioactivity in this kind of Schiff base.
Journal ArticleDOI
SoxS regulates the expression of the Salmonella enterica serovar Typhimurium ompW gene.
Fernando Gil,Ismael Hernández-Lucas,Rubén Polanco,Nicolás Pacheco,B. Collao,José M. Villarreal,Gino Nardocci,Edmundo Calva,Claudia P. Saavedra +8 more
TL;DR: Electrophoretic mobility shift assays and footprinting experiments showed that SoxS binds at a region that starts close to -54 and ends at about -197 upstream of the transcription start site, which suggests that the ompW gene has a class I SoxS-dependent promoter.
