Hi James,
These tutorials may also be worth a look, or at least a glance to see if they cover things you want to know about:

Structure Analysis and Comparison

Functional Annotation Scenario: The Structure-Function Linkage Database (SFLD) and Chimera

I’m not aware of plugins, but Chimera’s Multalign Viewer is very rich in features for this type of work; it includes a variety of options for calculating and displaying conservation, mostly provided via the included AL2CO program from the Grishin group. Anyway, that and much more is described in the new tutorial and links therein.

>> I'd like to perform analysis of the set of the sequences (presented in the FASTA multiple-alignment file) together with the some (not all) X-ray structures available for several of the sequences presented in its database to detect conservative motifs (from sequence) and make conclusions about its functional importance (based on the analysis of the Xray data) to make conclusions between conservation of sequence and it's functional relevance. Could you provide me with the some useful Chimera plugging as well as for some tutorials
