Both reactions occur simultaneously and in competition at the same active site. Although the small subunit is not catalytic it is essential for maximal activity.Heterohexadecamer of 8 large and 8 small subunits.The basic functional RuBisCO is composed of a large chain homodimer in a 'head-to-tail' conformation. In form I RuBisCO this homodimer is arranged in a barrel-like tetramer with the small subunits forming a tetrameric 'cap' on each end of the 'barrel'.Belongs to the RuBisCO small chain family.Ribulose bisphosphate carboxylase small subunit41032005-11-081151062fe92959e97977d9ef27793de69540ddMRITQGCFSFLPDLTDAQISAQVDYCLGRGWAVSLEHTDDPHPRNTYWEMWGMPMFDLRDPKGVMIELDECRKAWPGRYIRINAFDSTRGFETVTMSFIVNRPEVEPSLRMERTEVDGRSIRYTHSIVR
