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. 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 HIGH B-FACTORS 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.
