cDNA cloning and genetic analysis of a novel decolorizing enzyme, peroxidase gene dyp from Geotrichum candidum Dec 1.
A novel decolorizing peroxidase gene (dyp) was cloned from a cDNA library of a newly isolated strain of fungus Geotrichum candidum Dec 1. The open reading frame of 1494 nucleotides which corresponds to dyp predicts a primary translation product of 498 amino acids, M(r) 53,306. The deduced amino acid sequence of DyP does not contain the typical conserved motif which is characteristic of heme-containing peroxidases in the plant peroxidase superfamily. Comparison of the deduced amino acid sequence of DyP with that of a peroxidase from Polyporaceae sp. suggests that these proteins share highly homologous regions.
