As a matter of fact, no, it is not. But it must be available soon!
Yours,

Dear all,
I am working currently on a structure that, nicely, presents
two different orientations between its domains when one compares
monomers of the tetramer in the asymmetric unit.
I notice, in this nature gift, that a helix, probably central
(in its role) for the relation (orientation) between the two
domains, assumes different relation to other one (helix, that
belongs to one of the domains) such that they are (significantly)
more or less "coiled-coiled"one to another, once the domains are
in the "close" or "open" conformation. We have already analyzed
the hydrogen bonds and salt bridges that are disrupted (or formed)
due to the different (domain and helix) conformations.
I wonder whether there is a metric (easy to evaluate) to
characterize how much the two helix are "around each other" (id
est, how much "coiled-coiled" they are) and, preferably, a
software to calculate this metric.
Thank you,
