Description
1. TR517 Refinement 159 X-RAY 2010-06-24 2010-07-15 2010-07-15 One of the best submitted models according to the GDT_TS. Starting model GDT_TS=69. All residues are present in the experimental structure. No residues were trimmed from the model. A popular among predictors template lacks the region corresponding to res. 65-88 in the target. This region and the neighboring residues are poorly modeled in all the models submitted and should get the main attention in refinement.  
2. TR530 Refinement 115 X-RAY 2010-06-25 2010-07-16 2010-07-16 One of the best submitted server models. Starting MODEL is quite accurate: GDT_TS=80. Residues 1-29 are absent from the experimental structure. Additional 6 residues (up to the position 35) are cut out as not participating in the crystal contacts of the monomer. Loops 45-58 and 75-79 are modeled inaccurately. They do not participate in the intra-chain contacts.  
3. TR567 Refinement 145 X-RAY 2010-06-28 2010-07-19 2010-07-19 One of the best submitted server models. Starting MODEL is quite accurate: GDT_TS=78. Residues 1-3 are absent from the experimental structure and deleted from the model. Loops around res. 63 and 103 deviate the most from the native structure.  
4. TR568 Refinement 158 X-RAY 2010-06-28 2010-07-19 2010-07-19 One of the best submitted server models. The native structure misses regions 1-22 and 42-54. Starting MODEL has quite low score GDT_TS=43, in part because residues up to approx. 62 (those that have correspondent residues in the experimental structure) are folded incorrectly. Residues 1-61 are trimmed and the rest of the model is suggested for the refinement. There are several regions worth attention, in particular two loops around res. 102 and 116 are substantially off.  
5. TR557 Refinement 145 NMR 2010-06-28 2010-07-19 2010-07-19 One of the best submitted server models. Starting MODEL has GDT_TS=67. Residues 126-145 are trimmed from the experimental structure as showing big deviation in different models of the NMR ensemble. They are also deleted from the starting model. The model has several regions for refinement, in particular loops around res. 15 and 61.  
6. TR569 Refinement 79 NMR 2010-06-29 2010-07-20 2010-07-20 One of the best submitted server models. Starting model GDT_TS=73. Several loops are off. The biggest deviation from the native structure - in the region 50-60.  
7. TR576 Refinement 172 X-RAY 2010-07-02 2010-07-23 2010-07-23 One of the best submitted models. Starting MODEL GDT_TS=65. Residues 1-24 and 163-172 are absent from the experimental structure and deleted from the model. Starting model has several areas for refinement, in particular C-terminal (res. 120 and on). Region 57-65 can also be essentially improved.  
8. TR574 Refinement 126 X-RAY 2010-07-02 2010-07-23 2010-07-23 One of the best submitted models. Starting MODEL GDT_TS=62. Residues 1-24 are absent from the experimental structure and deleted from the model. Multiple regions can be refined.  
9. TR594 Refinement 140 X-RAY 2010-07-12 2010-08-02 2010-08-02 One of the best submitted models. Starting model GDT_TS=86. All best models are quite accurate. Major area for the refinement - around res. 110. Practically all other loops can be improved. There is some substantial side chain mis-packing in the area of the central cavity of the experimental structure. An IPA molecule present there is probably not responsible for the packing differences.  
10. TR592 Refinement 144 X-RAY 2010-07-12 2010-08-02 2010-08-02 One of the best submitted models. Starting model GDT_TS=75. All best models are quite accurate. Relatively low score is mainly due to improper folding of the C-term starting from the residue 122. Main areas for refinement - loops around 63 and 33. Helix 1-16 participate in crystal contacts of the pentamer and is cut off. The same pertains to the residues 122 and further.  
11. TR606 Refinement 169 X-RAY 2010-07-16 2010-08-06 2010-08-06 One of the best submitted server models. Starting MODEL GDT_TS=72. The experimental construct is missing residues 1-45 and 169. Structure has some packing issues. Conformation of the first ten (46-55) and the last twenty+ residues of the proposed model can be essentially improved.  
12. TR614 Refinement 135 X-RAY 2010-07-23 2010-08-13 2010-08-13 Unlike other refinement targets, two models are suggested as starting points here. These are the two best server models received on T0614 (GDT_TS around 70). Each of these models has different bits of the structure modeled better than the other one. Predictors are free to use only one of the suggested models as a starting point for the refinement or combine information from both of them. But remember, that this is only one refinement target. The experimental structure misses residues 1, 123-135, which were trimmed from the models.  
13. TR622 Refinement 138 X-RAY 2010-07-23 2010-08-13 2010-08-13 One of the best submitted server models. Starting MODEL GDT_TS=67. This is quite an accurate model up to res. 91 (even though some loops still can be improved). The most challenging area for the refinement is the C-terminal region starting from residue 97, where the model essentially departs from the native structure. The two chains of the structure have quite extensive contact interface but residues 103 and further are not part of this interface. The experimental structure misses residues 123-138, which are also trimmed from the starting model.  
14. TR624 Refinement 81 X-RAY 2010-07-30 2010-08-20 2010-08-20 This is the one of the most challenging refinement targets. Best model GDT_TS=56, AL0=52. There are big deviations from the native structure in the areas around res. 14, 24 and 54. The experimental structure misses residues 1-4, 74-81, which are trimmed from the model.
