    127127== Alternative from Elaine for glycosylation part ==
    128128
    129 Instead of showing glycosylation consensus sites on the single sequence, you could use Matchmaker to superimpose HIV1 gp120 and glycosylated SIV gp120 and show the corresponding pairwise sequence alignment.  Regions that superimpose well are automatically highlighted with orange boxes, and consensus glycosylation sites can then be highlighted on both sequences.

    131 Say 1gc1 chain G (HIV gp120) is already open as model 0, 3fus (glycosylated SIV gp120) as model 1.  Then you could focus on the SIV structure (e.g. focus #1) and show the glycosylation (alias glyco #1 & ~ protein; show glyco).  Then discuss glycosylation. May want show attached Asn residues (disp #1:asn & glyco z<4) or fill sugar rings (fillring glyco) or just hide all the atoms (~disp).  Then superimpose the structures and show the pairwise sequence alignment:

     139If the display is too busy, could hide the atoms at some point (~disp).

    137 The orange boxes on the sequence alignment are the parts used in the final fit and coincide with low values of the RMSD header (in pairwise case collapses to simply CA-CA distance).  Clicking the orange region selects the corresponding parts of the structures.

    141 Edit... Find PROSITE Pattern N-x-[ST] on both sequences reveals commonalities and differences.
