Predicted normalized B-factor
|
(B-factor is a value to indicate the extent of the inherent thermal
mobility of residues/atoms in proteins. In I-TASSER, this value is
deduced from threading template proteins from the PDB in combination with the
sequence profiles derived from sequence databases. The reported B-factor
profile in the figure below corresponds to the normalized B-factor of the
target protein, defined by B=(B'-u)/s, where B' is the raw B-factor
value, u and s are respectively the mean and standard deviation of the raw
B-factors along the sequence.

Top 10 threading templates used by I-TASSER
|
(I-TASSER modeling starts from the structure templates identified by LOMETS from the PDB library.
LOMETS is a meta-server threading approach containing multiple threading programs,
where each threading program can generate tens of thousands of
template alignments. I-TASSER only uses the templates of the highest significance in the threading alignments,
the significance of which are measured by the Z-score, i.e. the difference between the raw and average scores
in the unit of standard deviation. The templates in this section are the 10 best templates selected from
the LOMETS threading programs. Usually, one template of the highest Z-score is selected from each threading program, where the threading programs are sorted by the average performance in the large-scale benchmark test experiments.)

| (a) | All the residues are colored in black; however, those residues in template which are identical to the residue in the query sequence are highlighted in color. Coloring scheme is based on the property of amino acids, where polar are brightly coloured while non-polar residues are colored in dark shade. (more about the colors used) |
| (b) | Rank of templates represents the top ten threading templates used by I-TASSER. |
| (c) | Ident1 is the percentage sequence identity of the templates in the threading aligned region with the query sequence. |
| (d) | Ident2 is the percentage sequence identity of the whole template chains with query sequence. |
| (e) | Cov represents the coverage of the threading alignment and is equal to the number of aligned residues divided by the length of query protein. |
| (f) | Norm. Z-score is the normalized Z-score of the threading alignments. Alignment with a Normalized Z-score >1 mean a good alignment and vice versa. |
| (g) | Download Align. provides the 3D structure of the aligned regions of the threading templates. |

Top 5 final models predicted by I-TASSER
|
(For each target, I-TASSER simulations generate a large ensemble of
structural conformations, called decoys. To select the final models, I-TASSER uses the SPICKER program to cluster
all the decoys based on the pair-wise structure similarity, and reports up to five models which
corresponds to the five largest structure clusters. The confidence of each model is quantitatively
measured by C-score that is calculated based on the significance of threading template alignments
and the convergence parameters of the structure assembly simulations.
C-score is typically in the range of [-5, 2], where a C-score of a higher value signifies a model with a higher
confidence and vice-versa. TM-score and RMSD are estimated based on C-score and protein length following
the correlation observed between these qualities. Since the top 5 models are ranked by the cluster size,
it is possible that the lower-rank models have a higher C-score in
rare cases. Although the first model has a better
quality in most cases, it is also possible that the lower-rank models have a better quality than the
higher-rank models as seen in our benchmark tests. If the I-TASSER simulations converge, it
is possible to have less than 5 clusters generated; this is usually an indication that the
models have a good quality because of the converged simulations.)

| Proteins structurally close to the target in the PDB (as identified by TM-align) |
(After the structure assembly simulation, I-TASSER uses the TM-align structural alignment program to match the first I-TASSER model to all structures in the PDB library. This section reports the top 10 proteins from the PDB that have the closest structural similarity,
i.e. the highest TM-score, to the predicted I-TASSER model. Due to the structural similarity, these proteins often have similar function to the target. However, users are encouraged to use the data in the next section 'Predicted function using COACH' to infer the function of the target protein, since COACH has been extensively trained to derive biological functions from multi-source of sequence and structure features which has on average a higher accuracy than the function annotations derived only from the global structure comparison.)

Top 10 Identified stuctural analogs in PDB
| (a) | Query structure is shown in cartoon, while the structural analog is displayed using backbone trace. |
| (b) | Ranking of proteins is based on TM-score of the structural alignment between the query structure and known structures in the PDB library. |
| (c) | RMSDa is the RMSD between residues that are structurally aligned by TM-align. |
| (d) | IDENa is the percentage sequence identity in the structurally aligned region. |
| (e) | Cov represents the coverage of the alignment by TM-align and is equal to the number of structurally aligned residues divided by length of the query protein. |
|
|
(This section reports biological annotations of the target
protein by COFACTOR and COACH based on the I-TASSER structure prediction.
While COFACTOR deduces protein functions (ligand-binding sites, EC and GO)
using structure comparison and protein-protein networks,
COACH is a meta-server approach that combines multiple function
annotation results (on ligand-binding sites) from the COFACTOR,
TM-SITE and S-SITE programs.)
