Substrate specificities
The founding member of glycoside hydrolase family 144 is endo-β-1,2-glucanase (EC3.2.1.71) from a soil bacterium Chitinophaga pinensis, which hydrolize β-1,2-linked glucan to produce a wide spectrum of corresponding oligosaccharides. This family also includes a sophorohydrolase (nonreducing end), which cleaves shorter β-1,2-glucan to release sophorose (Glc-β-1,2-Glc). From sequence analysis, endo-β-1,2-glucanase activity was major one.
