| Research Abstract |
We revealed three chitin binding proteins (CBPs) from Streptomyces griseus boosted enzymatic solubilization of - and -chitin. The amount of (GlcNAc)2 from the best combination with one of the CBP and a chitinase was about 30 times higher than that without the CBP after 24 h incubation.We proved crystallinity was affected to -chitin solubilization by using a commercially available enzyme from S. griceus or the chitinolytic system in Serratia marcescens.
