THE CTF PARAMETERS WERE REMARK 3 ESTIMATED ON THE MOVIE FRAMES BY CTFFIND4.1. BAD IMAGES SHOWING REMARK 3 CONTAMINATION, A DEFOCUS BELOW OR ABOVE 0.4 AND -3UM OR A BAD REMARK 3 CTF ESTIMATION WERE DISCARDED, RESULTING IN 4863 IMAGES USED FOR REMARK 3 FURTHER ANALYSIS WITH THE SOFTWARE PACKAGE RELION2.1. ABOUT 3000 REMARK 3 PARTICLES WERE PICKED MANUALLY TO GENERATE 2D REFERENCES WHICH REMARK 3 WHERE IMPROVED IN SEVERAL ROUNDS OF AUTOPICK. A LOW THRESHOLD REMARK 3 WAS USED DURING THE FINAL AUTOPICK STEP TO ENSURE THAT NO REMARK 3 PARTICLES ARE MISSED YIELDING MORE THAN A MILLION PARTICLES. REMARK 3 PARTICLES WERE EXTRACTED WITH A BOX SIZE OF 240 PIXELS, AND REMARK 3 INITIAL CLASSIFICATION STEPS WERE PERFORMED WITH THREE-FOLD REMARK 3 BINNED DATA. FALSE POSITIVES OR BAD PARTICLES WERE REMOVED IN REMARK 3 FIRST ROUNDS OF 2D CLASSIFICATION, RESULTING IN 628,015 REMARK 3 PARTICLES THAT WERE FURTHER SORTED IN SEVERAL ROUNDS OF 3D REMARK 3 CLASSIFICATION. A MAP GENERATED FROM THE GLTPH STRUCTURE (PDB ID REMARK 3 3KBC) WAS USED AS REFERENCE FOR THE FIRST ROUND, AND THE BEST REMARK 3 OUTPUT CLASS WAS USED IN SUBSEQUENT JOBS IN AN ITERATIVE WAY. REMARK 3 THE BEST 3D CLASS, COMPRISING 184,080 PARTICLES FROM 4859 IMAGES, REMARK 3 WAS SUBJECTED TO AUTO-REFINEMENT, YIELDING A MAP WITH A REMARK 3 RESOLUTION OF 4.26 A BEFORE MASKING AND 3.91 A AFTER MASKING. REMARK 3 PARTICLES WERE FURTHER POLISHED IN RELION VERSION 2.1 AND REMARK 3 SUBJECTED TO ANOTHER ROUND OF 2D AND 3D CLASSIFICATION RESULTING REMARK 3 IN A FINAL DATASET OF 133,437 PARTICLES. THE FINAL POLISHED MAP REMARK 3 HAD A RESOLUTION OF 4.26 A BEFORE MASKING AND 3.85 A AFTER REMARK 3 MASKING. THE MAP WAS SHARPENED USING AN ISOTROPIC B-FACTOR OF - REMARK 3 171 A2, FOR MANUAL INSPECTION A B-FACTOR OF -225 A2 WAS USED. REMARK 3 THE APPROACH OF FOCUSED REFINEMENT, WHERE THE LESS-RESOLVED REMARK 3 DETERGENT MICELLE WAS SUBTRACTED FROM THE PARTICLE IMAGES, DID REMARK 3 NOT IMPROVE RESOLUTION. DURING 3D CLASSIFICATION AND AUTO- REMARK 3 REFINEMENT JOBS A C3-SYMMETRY WAS IMPOSED. TO CHECK FOR REMARK 3 CONFORMATIONAL HETEROGENEITY OF THE DATA, WHERE SINGLE PROTOMERS REMARK 3 WITHIN THE TRIMER MIGHT ADOPT A DIFFERENT CONFORMATION, 3D REMARK 3 CLASSIFICATIONS WITH NO SYMMETRY IMPOSED WERE PERFORMED AT REMARK 3 DIFFERENT STAGES OF IMAGE PROCESSING. WE FURTHER PERFORMED 3D REMARK 3 CLASSIFICATION ON THE INDIVIDUAL PROTOMERS OF A SINGLE REMARK 3 TRANSPORTER USING SYMMETRY EXPANSION AND SIGNAL SUBTRACTION. REMARK 3 BOTH APPROACHES SHOWED NO INDICATION OF THE EXISTENCE OF A REMARK 3 DIFFERENT CONFORMATION. LOCAL RESOLUTION ESTIMATES WERE REMARK 3 ESTIMATED BY RELION. ALL RESOLUTIONS WERE ESTIMATED USING THE REMARK 3 0.143 CUT-OFF CRITERION WITH GOLD-STANDARD FOURIER SHELL REMARK 3 CORRELATION (FSC) BETWEEN TWO INDEPENDENTLY REFINED HALF MAPS. REMARK 3 DURING POST-PROCESSING, THE APPROACH OF HIGH-RESOLUTION NOISE REMARK 3 SUBSTITUTION WAS USED TO CORRECT FOR CONVOLUTION EFFECTS OF REAL- REMARK 3 SPACE MASKING ON THE FSC CURVE.
