CRYSTAL STRUCTURE OF APOCAROTENOID CLEAVAGE OXYGENASE FROM SYNECHOCYSTIS, NATIVE ENZYME
Overview
Enzymes that produce retinal and related apocarotenoids constitute a, sequence- and thus structure-related family, a member of which was, analyzed by x-ray diffraction. This member is an oxygenase and contains an, Fe2+-4-His arrangement at the axis of a seven-bladed beta-propeller chain, fold covered by a dome formed by six large loops. The Fe2+ is accessible, through a long nonpolar tunnel that holds a carotenoid derivative in one, of the crystals. On binding, three consecutive double bonds of this, carotenoid changed from a straight all-trans to a cranked cis-trans-cis, conformation. The remaining trans bond is located at the dioxygen-ligated, Fe2+ and cleaved by oxygen.
