[https://www.uniprot.org/uniprot/RBCX_THEVB RBCX_THEVB] An RbcL-specific chaperone. Required for assembly of the RbcL8 core (PubMed:19081849) (Probable). The central cleft of the RbcX homodimer (RbcX2) binds the C-terminus of a RbcL monomer, stabilizing the C-terminus and probably preventing its reassociation with chaperonin GroEL-ES. At the same time the peripheral region of RbcX2 binds a second RbcL monomer, bridging the RbcL homodimers in the correct orientation. The RbcX2(2)-bound RbcL dimers then assemble into the RbcL8 core (RbcL8-(RbcX2)8). RbcS binding triggers the release of RbcX2 (By similarity).[UniProtKB:Q44212]<ref>PMID:19081849</ref> <ref>PMID:21821880</ref>
