ALKYLDIHYDROXYACETONEPHOSPHATE SYNTHASE IN P1

Overview

Ether phospholipids are essential constituents of eukaryotic cell, membranes. Rhizomelic chondrodysplasia punctata type 3 is a severe, peroxisomal disorder caused by inborn deficiency of, alkyldihydroxyacetonephosphate synthase (ADPS). The enzyme carries out the, most characteristic step in ether phospholipid biosynthesis: formation of, the ether bond. The crystal structure of ADPS from Dictyostelium, discoideum shows a fatty-alcohol molecule bound in a narrow hydrophobic, tunnel, specific for aliphatic chains of 16 carbons. Access to the tunnel, is controlled by a flexible loop and a gating helix at the, protein-membrane interface. Structural and mutagenesis investigations, identify a cluster of hydrophilic catalytic residues, including an, essential tyrosine, possibly involved in ... [(full description)]
