[[https://www.uniprot.org/uniprot/RBCX_NOSS1 RBCX_NOSS1]] An RbcL-specific chaperone. The central cleft of the RbcX homodimer (RbcX2) binds the C-terminus of an 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.[HAMAP-Rule:MF_00855] When rbcL-rbcX-rbcS or rbcL-rbcS were overexpressed in E.coli no change in reconstituted RuBisCO activity was observed, which suggests RbcX plays no role in RuBisCO assembly in this system (PubMed:8472962). However in PubMed:8472962 E.coli chaperones groL and groS were also overexpressed, which may compensate for lack of rbcX (Probable).<ref>PMID:8472962</ref> <ref>PMID:15564522</ref> | |||
