Transcription factor Ace1 from Saccharomyces cerevisiae regulates the expression of target genes when the copper concentration reaches 200 ìÌ levels. We are studying the ortholog of Ace1 from fungus Phanerochaete chrysosporium PcACE1, isolated by c

The expression of the acetyl xylan esterase II (axeII) gene from Penicillium purpurogenum is repressed by glucose and induced by xylan, as well as to a small degree by xylose and xylitol. This gene is expressed at neutral pH, but not under alkaline o

Penicillium purpurogenum produces several endoxylanases, two of which (XynA and XynB) have been purified and characterized. XynB has been sequenced, and it belongs to glycosyl hydrolase family 11. In this publication we report the structure of the xy

The biotechnological applications of cheese-ripening fungi have been limited by a lack of genetics tools, in particular the identification and characterization of suitable promoters for protein expression. In this study, the suitability of the glycer

We have previously identified and functionally characterized the transcription factor ACE1 (Pc-ACE1) from Phanerochaete chrysosporium. In Saccharomyces cerevisiae, ACE1 activates the copper-dependent transcription of target genes through a DNA sequen

Zinc and copper are atypical modulators of ligand-gated ionic channels in the central nervous system. We sought to identify the amino acids of the rat P2X4 receptor involved in trace metal interaction, specifically in the immediate linear vicinity of

At least three acetyl xylan esterases (AXE I, II and III) are secreted by Penicillium purpurogenum. This publication describes more detailed work on AXE I and its gene. AXE I binds cellulose but not xylan; it is glycosylated and inactivated by phenyl

Integrin-mediated encounters of T cells with extracellular cues lead these cells to adhere to a variety of substrates and acquire a spread phenotype needed for their tissue incursions. We studied the effects of galectin-8 (Gal-8), a beta-galactoside

To assess the mechanism of P2X2 receptor modulation by transition metals, the cDNA for the wild-type receptor was injected to Xenopus laevis oocytes and examined 48-72 h later by the two-electrode voltage-clamp technique. Copper was the most potent o
