PYRUVOYL DEPENDENT ASPARTATE DECARBOXYLASE
Overview
The structure of L-aspartate-alpha-decarboxylase from E. coli has been, determined at 2.2 A resolution. The enzyme is a tetramer with, pseudofour-fold rotational symmetry. The subunits are six-stranded, beta-barrels capped by small alpha-helices at each end. The active sites, are located between adjacent subunits. The electron density provides, evidence for catalytic pyruvoyl groups at three active sites and an ester, at the fourth. The ester is an intermediate in the autocatalytic, self-processing leading to formation of the pyruvoyl group. This, unprecedented structure provides novel insights into the general, phenomenon of protein processing.
