Laccases from basidiomycetes are efficient enzymes in the degradation of xenobiotics. In this study we aimed to provide an industrially relevant expression system for Lentinula edodes laccases, to characterize their enzymatic properties, and to evaluate their potential in bioremediation. Two 1573-bp allelic laccase genes from L. edodes L54 were cloned based(More)
Laccases are versatile biocatalysts for the bioremediation of various xenobiotics, including dyes and polyaromatic hydrocarbons. However, current sources of new enzymes, simple heterologous expression hosts and enzymatic information (such as the appropriateness of common screening substrates on laccase engineering) remain scarce to support efficient(More)
Metergoline possesses potent antifungal activity against Candida krusei, a notorious yeast species that is inherently resistant to the common antifungal agents. In an attempt to elucidate the action mechanisms of metergoline, the present study was designed to investigate its effects on a number of classical markers of apoptosis in C. krusei. The results(More)
The industrial importance of Trigonopsis variabilisd-amino acid oxidase (TvDAAO) is represented by its biocatalytic oxidative deamination of cephalosporin C (CPC) to yield glutaryl-7-aminocephalosporanic acid (GL-7-ACA). The process has been incorporated into a two-step bioconversion to produce 7-aminocephalosporanic acid, the crucial synthetic nucleus for(More)
Growth hormone (GH), or somatotropin, is a protein that may enhance physical performance and facilitate growth and wound healing. For this reason, growth hormones and their recombinant analogues are prohibited in human sports by the World Anti-Doping Agency (WADA) and in horseracing under Article 6 of the International Agreement on Breeding, Racing and(More)
Candida kefyr is a common yeast species that can be found in fermented milk and cheeses. As a first step to developing a gene transfer system for C. kefyr, the orotidine-5'-phosphate decarboxylase (URA3) gene was cloned, using degenerate PCR and genome walking. The uninterrupted open reading frame of the C. kefyr URA3 gene spans 801 bp, corresponding to 267(More)
