Insight into kinetics and thermodynamics of a novel hyperstable GH family 10 endo-1,4-β-xylanase (TnXynB) with broad substrates specificity cloned from Thermotoga naphthophilaRKU-10T

Currently, hyperstable endo-1,4-β-xylanase has been the focus of attention as potent biocatalyst as well as utilization in bioconversion process. Therefore, the gene (1035 bp) of a monomeric glycoside hydrolase family 10 (GH10) endo-1,4-β-xylanase (TnXynB) from a hyperthermophilic eubacterium Thermotoga naphthophila RKU-10T was cloned and overexpressed in a mesophilic host system. The extracellular TnXynB was purified to homogeneity with a...
