Figure 3From: Novel β-N-acetylglucosaminidases from Vibrio harveyi 650: Cloning, expression, enzymatic properties, and subsite identificationSpecific hydrolyzing activity of V. harveyi GlcNAcases. The enzymic activity of Vh Nag1 and Vh Nag2 was determined using the colorimetric assay for p NP-glycoside substrates and using the reducing sugar assay for chitooligosaccharides substrates. The reactions were set up as described in the text.Back to article page
