6QX9

Structure of a human fully-assembled precatalytic spliceosome (pre-B complex).


Structural Similarities for the Entities in PDB 6QX9

The following structural similarities have been found using the jFATCAT-rigid algorithm [1,2].

To reduce the number of hits, a 40% sequence identity clustering has been applied and a representative chain taken from each cluster. If the representative chain consists of multiple domains, each domain is included in the search. If available, the SCOP 1.75 domain assignment [3] is used. Otherwise algorithmic domain assignments are computed using the ProteinDomainParser [4].

Currently viewing only significant results (P-value < 0.001). Show all available results.

Cluster data are up-to-date as of: Sep-27-2017
