CRYSTAL STRUCTURE OF MERCURY DERIVATIVE OF RETINOL DEHYDRATASE IN A COMPLEX WITH RETINOL AND PAP
Overview
We report here the crystal structure of retinol dehydratase, an enzyme that catalyzes the synthesis of anhydroretinol. The enzyme is a member of the sulfotransferase superfamily and its crystal structure reveals the insertion of a helical lid into a canonical sulfotransferase fold. Site-directed mutations demonstrate that this inserted lid is necessary for anhydroretinol production but not for sulfonation; thus, insertion of a helical lid can convert a sulfotransferase into a dehydratase.
About this Structure
1FMJ is a Single protein structure of sequence from Spodoptera frugiperda with , , and as ligands. Full crystallographic information is available from OCA.
