How do I use sequence numbers target a range of residues?
Suppose you want to target the range of sequence numbers 22-33. In the Find.. dialog, enter “22-33” to put halos around the 12 residues from 22 through 33. Now click Contacts… There, check Target Atoms with Halos. Now you are ready to Show Atoms Contacting Target. If there is more than one chain with residues 22-33, append a colon followed by the chain name you want. For chain B, enter “22-33:b” in Find… The mechanism used to select unnamed chains is detailed in Technical Information. • Contacting Atoms: Definitions The Contacts.. dialog in FirstGlance shows atoms likely to be noncovalently (or covalently) bonded to any target set of atoms that you select. Such atoms are deemed “contacts”, and are shown as spheres (either of van der Waals radii, or of smaller radii in “ball and stick” rendering). “Contacting” atoms are determined solely by distance from the target, using the following criteria. Suggestions for improving the following criteria are welcome (see feedback address at th
