However, the β active
site can slowly hydrolyze this substrate with MUG/MUGS ratios of
~300:1 for Hex-B and 3.7:1 for Hex-A [19]. Thus each of the %-residual
Hex-A values reported in Table 1 is multiplied by 3.7 and is varying
from 0% to 3.1%, which is in accordance with the previously reported
value.
