For example, the mutual … Webβ-Xylose lacks a C6-OH side chain, so the active site may have evolved without the opportunity for stabilization of the TS by a gg C6-OH interaction. Instead, the catalytic acid/base, which acquires negative charge by proton transfer, is in close proximity to the pyranose O5 and C1 atoms thereby stabilizing the positive charge that develops on …
