Cell surface beta-glucosidase involved in cell wall biosynthesis and septation, and thus required for normal growth and correct hyphal morphogenesis. Has hydrolytic activity on linear (1->3)-beta-D-glucans such as laminaribiose and other laminarioligosaccharides. Has also a minor transferase activity. Optimum pH is 5.5. Optimum temperature is 37 degrees Celsius. Expression was detected 4h after the initiation of spore germination and during mycelial growth. Highly glycosylated. Leads to smaller colonies and swollen and vacuolated hyphae with double cell wall and leaky tips. Leads also to decreased conidiation. Belongs to the SUN family.
