Overview

This page will provide a table (and eventually a full lexicon article) on the spatial positioning of the catalytic general acid residue in the active sites of glycoside hydrolases. The table below updates those found in the seminal paper on this concept by Heightman and Vasella [1], and the more recent summary by Nerinckx et al. [2].
