Protein Domain : Allophycocyanin linker protein IPR011134

Type	Family
Description	Members of this family are linker polypeptides that are associated with phycobilisomes. Phycobiliproteins (biliproteins) are accessory pigments thatserve as receptors of light energy for photosystem II. Phycobilisomes are highly organised complex structures of biliproteins and linker polypeptides.The linker polypeptides are involved in the attachment of phycobilisomes to the thylakoid membrane and in the assembly of biliproteins intophycobilisomes.The three dimensional structure of an electrophoretically purified allophycocyanin-linker complex has beendetermined [ ]. The asymmetric unit contains twoside-to-side associated trimeric (alphabeta) 3allophycocyanin complexes comprising the linker polypeptide in a defined orientation insidethe trimer. The linker representing a protein fold related to the prosegment of procarboxypeptidase A is in contact with only two of the threebeta-subunits and directly interacts with the corresponding chromophores of these proteins.For additional information please see [ , ].
