Effect of the point mutation XlnRA871V on the production of extracellular enzymes on wheat bran. FPase (a), pNPCase (b), CMCase (c), pNPGase (d), xylanase (e) and pNPXase activities (f), and extracellular protein concentrations (g) of supernatants from wild-type, xlnR A871V, and gpdA(p)::xlnR strains were analyzed. All error bars represent the standard deviations. Statistical significance of the differences between wild-type and xlnR A871V at 120 h was calculated. *p < 0.05, **p < 0.01, ***p < 0.001. h SDS-PAGE analysis of the supernatants of the wild-type and xlnR A871V strains. The protein bands 1–5 were identified by MS–MS as listed in Table 2
