Abstract
This work was performed to test the alpha-glucuronidase-producing abil ity of basidiomycetes (70 species) using 2-O-(alpha-D-glucopyranosylur onic acid)-D-xylose (GA-2X) and p-nitrophenyl alpha-D-glucopyranosylur onic acid (PNP-GA) as substrates for the enzyme reaction. The crude en zyme preparations originating from five basidiomycetes, such as Coriol us pubescens, Irpex lacteus, Merulius tremellosus, and so forth, hydro lyzed GA-2X, but they did not hydrolyze PNP-GA. The results lead to th e conclusion that the two substrates are hydrolyzed by different enzym es.
