EFFECTIVE RESOLUTION OF THE REMARK 3 RECONSTRUCTION: THE RESOLUTION OF THE FINAL RECONSTRUCTED DENSITY REMARK 3 WAS DETERMINED TO BE AT LEAST 15 ANGSTROMS, AS MEASURED BY REMARK 3 RANDOMLY SPLITTING THE PARTICLES INTO TWO SETS AND CALCULATING REMARK 3 THE FOURIER SHELL CORRELATIONS BETWEEN THE TWO INDEPENDENT SET. REMARK 3 (HEEL, 1987, ULTRAMICROSCOPY 21, 95-100). 1IA0 IS AN ATOMIC MODEL REMARK 3 OF KIF1A HEAD-MICROTUBULE COMPLEX, WHICH CONTAINS KIF1A, ALPHA- REMARK 3 TUBULIN, AND BETA-TUBULIN. SINCE ALPHA- AND BETA-TUBULIN WERE REMARK 3 INDISTINGUISHABLE AT 15A RESOLUTION, THE ASSIGNMENT OF ALPHA- AND REMARK 3 BETA-TUBULIN WAS ARBITRARY WHEN 1IA0 WAS DEPOSITED. AUTHORS STATE REMARK 3 THAT THEY WERE AWARE OF THE LIMITATION AND DIDN'T MENTION ABOUT REMARK 3 THE ASSIGNMENT OF ALPHA- AND BETA-TUBULIN IN THE RELEVANT 2001 REMARK 3 NATURE PAPER. THEREFORE, THE MAIN CONCLUSIONS IN THE PAPER ARE REMARK 3 STILL HOLD TRUE. HOWEVER, SUBSEQUENTLY THE ASSIGNMENT OF ALPHA- REMARK 3 AND BETA-TUBULIN TURNED OUT TO BE WRONG AND SHOULD BE SWAPPED. REMARK 3 FOR THE CORRECT ASSIGNMENT AND BETTER STRUCTURES, PLEASE USE REMARK 3 2HXF. THIS IS BASED ON HIGHER RESOLUTION (10 ) STRUCTURE, WHICH REMARK 3 WAS PUBLISHED IN EMBO J. 2006. 25:4187-4194.

A DROP OF THE REMARK 245 POLYMERIZED MICROTUBULE WAS PLACED ON THE HOLEY CARBON FILM ON REMARK 245 THE EM-GRID AND LEFT FOR 10 S IN THE HUMID CHAMBER. THE REMARK 245 MICROTUBULE SOLUTION WAS THEN ABSORBED BY FILTER PAPER, AND A REMARK 245 DROP OF THE C351 SOLUTION (0.2 MG/ML) IN THE ASSAY BUFFER REMARK 245 (IMIDAZOLE 50 MM, MG-ACETATE 5 MM, EGTA 1 MM, K-ACETATE 50 MM, REMARK 245 DTT 10 MM, PACLITAXEL 10 MICRO M) WAS PUT ON THE GRID. REMARK 245 IMMEDIATELY AFTER THE ABSORPTION OF THE DROP, THE GRID WAS REMARK 245 PLUNGED INTO LIQUID ETHANE (-185C). THE SAMPLE CONSISTS OF A REMARK 245 KIF1A-DECORATED MICROTUBULE. THE EXPERIMENT DESCRIBES A REMARK 245 MICROTUBULE-RELATED PROCESS.
