Structural Similarities for the Entities in PDB 1E27

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: Jun-20-2017

Info & Help Documentation

A detailed description of the procedure for the all vs. all alignments is available.

Entity #1 | Chains A

Description: HLA CLASS I HISTOCOMPATIBILITY ANTIGEN HEAVY CHAIN protein | Length: 276

No structure alignment results are available for 1E27.A explicitly.

It is represented by chain 1K5N.a which has more than 90% sequence identity.

Show structure comparison results for representative 1K5N.a

Entity #2 | Chains B

Description: BETA-2 MICROGLOBULIN LIGHT CHAIN protein | Length: 99

No structure alignment results are available for 1E27.B explicitly.

It is represented by chain 1K5N.b which is 100% sequence identical.

Show structure comparison results for representative 1K5N.b

Entity #3 | Chains C

Description: HIV-1 PEPTIDE (LPPVVAKEI) protein | Length: 9

This entity is too short to be considered for the all vs. all structure alignments.
