4.1.1.11 | tetramer |
crystallographic data. 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 |

x * 2800, beta, + x * 11000, alpha, + x * 13800, pi, SDS-PAGE, enzyme comprises principally the unprocessed pi-subunit, with a small proportion of the alpha-subunit and the beta-subunit. The enzyme is synthesized initially as an inactive proenzyme, the pi-protein, which is proteolytically cleaved at a specific X-Ser bond to produce a beta-subunit with XOH at its C-terminus and an alpha-subunit with a pyruvoyl group at its N-terminus, derived from serine |
