Allophycocyanin linker chain (IPR011064)

Short name: Allophyco_linker_chain

Overlapping entries


This superfamily represents the Allophycocyanin linker chain domain.

The three dimensional structure of an electrophoretically purified allophycocyanin-linker complex has been determined [PMID: 9990029]. The asymmetric unit contains two side-to-side associated trimeric (alphabeta)3 allophycocyanin complexes comprising the linker polypeptide in a defined orientation inside the trimer. The linker representing a protein fold related to the prosegment of procarboxypeptidase A is in contact with only two of the three beta-subunits and directly interacts with the corresponding chromophores of these proteins.
