LITERATURE
evolution
the enzyme belongs to the GH16 endo-beta-1,3-1,4-glucanases family
physiological function
endo-beta-1,3-1,4-glucanases are glycoside hydrolases involved in the enzymatic depolymerization of 1,3-1,4-beta-glucans and show antifungal activity against some fungi. Bacillus amyloliquefaciens BLB369 has a high antagonistic activity against phytopathogenic fungi. The purified recombinant enzyme has the ability to inhibit the growth of the phytopathogenic fungus Alternaria alternata

enzyme shows the ability to inhibit the growth of phytopathogenic fungus Alternaria alternata
synthesis
construction of a fusion gene, encoding beta-1,3-1,4-glucanase both from Bacillus amyloliquefaciens and Clostridium thermocellum, via end-to-end fusion and expression in Escherichia coli. The catalytic efficiency of the fusion enzyme for oat beta-glucan is 2.7- and 20fold higher than that of the parental Bacillus amyloliquefaciens and Clostridium thermocellum enzymes, respectively, and the fusion enzyme can retain more than 50% of activity following incubation at 80°C for 30 min, whereas the residual activities of Bacillus amyloliquefaciens and Clostridium thermocellum enzymes are both less than 30%
