abstract：:Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is the key enzyme in the fixation of CO(2) in the Calvin cycle of plants. Many genome projects have revealed that bacteria, including Bacillus subtilis, possess genes for proteins that are similar to the large subunit of RuBisCO. These RuBisCO homologues are ca...
