I am not familiar with the priorities of global biotechnology
neverthelles taking into account benefits from protein folding and
function prediction and classification it is unclear why automatic
domains annotation is frighteninglydelayed compared with the amount of
Is it realy so difficult to construct reliable domains positioning tool
when strictly corelation between evolutionary order and the lack of
random events is obvious ?

As you may know, there are many different definitions of "domain" and different resources (database websites, web servers, publications, etc.) will say that the boundaries are in different places. How to quickly show these on the 3D structure depends on which resource you are using and what kind of information they provide. Further, I don't know if you are starting from only a structure or whether you have a sequence window already open.

> If the website or other resource shows the domain on the sequence rather than as residue numbers, another way is to show the sequence of your structure in Chimera (main menu: Favorites… Sequence) and then on the sequence drag a box around the desired part, which will also select the corresponding part of the structure. Then you can use the Actions menu to color the selected part, or command, e.g.: color red,r sel

Then you can use the Actions menu or command to color the selected part, as above. However, many UniProt entries don't have domain annotations.
