Laccase may work as a virulence factor in fungal pathogenesis. There are 16 laccase genes annotated in the Magnaporthe grisea genome database. In this study, we applied bioinformatics and gene knock-out techniques to study the function of laccase gene Mgg_00551.5 in the fungus. Bioinformatics analysis showed that the gene encodes a protein with three domains of poly-copper oxidase and being secreted into extra-cellular compartment. A slight decrease of laccase activity was observed in gene knock-out mutant ...

漆酶是一种含铜多酚氧化酶,由于首次从日本漆树(Rhus venicifera)的汁液中分离而得名(Yoshida,1883),能够催化酚类物质的氧化还原反应,使之生成相应的苯醌和水(季立才和胡培植,1996;Yaver et al.,1996)。随后人们发现一些高等真菌也能分泌这种酶。最新研究表明,细菌也可产漆酶?
