PECR associated with the peroxisomal membrane catalyzes the NADPH-dependent reduction of 2E-phytenoyl-CoA to form phytanoyl-CoA (Das et al. 2000; Gloerich et al. 2006). The active form of the enzyme is inferred to be a homotetramer from unpublished data deposited in PDB (accession 1YXM). This reaction is part of the process by which dietary phytol, ultimately derived from chlorophyll, is catabolized (Van Veldhoven 2010).
