Crystallographic characterization of the N-terminal domain of PEX1.
Peroxisomal enzymes are responsible for several primary metabolism pathways, including beta-oxidation and lipid biosynthesis. PEX1 and PEX6 are hexameric AAA-type ATPases and both are necessary for the import of more than 50 peroxisomal resident proteins from the cytosol into peroxisomes. In this study, PEX1 N-terminal domain crystals have been prepared. The crystals belong to space group P3(1) or P3(2), with unit-cell parameters a = b = 63.5 A, c = 33.5 A, and contain one protein molecule per crystallographic asymmetric unit. An intensity data set was collected to a resolution of 2.05 A.
