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