Interpreting I-TASSER output

Question

[kishorssf91]

Hi, Recently, i have received a protein structure result from I-TASSER. Here i have few questions to interpret the result:

1. 1. What does it mean by solvent accessibility value (0 to 9)? Does it mean near to 9 is more accessible to solvents? And if it likes so, is there any relation to solvent accessible site and ligand binding site? 2.In model figure how to mark the binding sites? As binding site information are just somewhat in written formet, but i was expecting the exact position in figure. 3.Acording to C-score of ligand binding sites, can i say someting like that "site 42(E) and 46(N) are candidate for Mg2+ binding?

Here, i am adding the link of my job: https://zhanglab.dcmb.med.umich.edu/I-TASSER/output/S639738/ and a modeled image.

Looking for your cooperation. Thanks.

i don't know why i was failing to attach it with question. Anyway i am attaching it with comment

Answer 1

Solvent accessible value simply indicates: 0 (buried residue) to 9 (highly exposed residue). Regarding your other query the Ligand binding site could be solvent accessible site but vice versa may not be true. The 42(E) and 46(N) are the ligand binding site for 2o1uB but C-score indicates less confidence score for your predicted structure active site. Maybe try with some active site prediction tools as well to co-confirm the region.
