RESIDUES 1-22 AND 163-191 ARE ABSENT IN MODEL AND IN ELECTRON DENSITY. THE N- AND C-TERMINI ARE DISORDERED IN APOE 22KD FRAGMENTS. THE N-TERMINAL MAIN CHAIN LIKELY SPLITS AT RESIDUE 22 AND SOME PARTIALLY OCCUPIED SOLVENT MOLECULES IN CLOSE PROXIMITY MAY IN FACT BE POORLY LOCALIZED FRAGMENTS OF THE ABSENT TERMINII. LOOP REGION 82-89 IS COMMONLY DISORDERED IN APOE MODELS. DENSITY IS POOR AND THE LOOP BACKBONE WAS MODELLED AFTER 1BZ4 AND IS LIKELY PRESENT IN MULTIPLE CONFORMATIONS. THE AUTHORS CAUTION THAT A NUMBER OF LOOP SIDE CHAIN ATOMS HAVE EXCESSIVE B-FACTORS >100 AND ARE PROBABLY NOT LOCALISED AT ALL. THE MOLECULE IS GENERALLY VERY FLEXIBLE IN THE LOOP DOMAIN AND HAS OVERALL HIGH B VALUES IN MOST MODELS. SEE SEGELKE ET AL PROT SCI 9:886-897 (2000) FOR THE BIOLOGICAL RELEVANCE OF FLEXIBILITY IN LIPID BINDING.
