Catalyzes the hydrolysis of levan with endo-type specificity. The products of levan hydrolysis are a mixture of fructose and a series of fructooligosaccharides up to 12-mer, with levantriose being the major oligosaccharide obtained. Is not active towards sucrose. Source: Recombinant protein corresponding to aa451-579 from bacillus sp. Levanase, fused to His-Tag at N-terminal, expressed in Yeast.
