Y69F | the barrier for conversion of the 4C1 chair to the more-stable 2,5B boat in the wild-type enzyme-substrate complex is significantly lower than it is for the mutant. The mutation reduces the degree of oxacarbenium-ion character in the proximal xylose ring of the enzyme-substrate complex | Niallia circulans |
