RBS_PRK_STRBO

This parts encodes the phosphoribulokinase (PRK) of Streptomyces bottropensis ATCC 25435 (BBa_K4370004) under the control of an RBS (BBa_B0034). The co-expression of this part with the form I RuBisCO large (BBa_K4370000, BBa_K4370002) and small (BBa_K4370001, BBa_K4370003) subunits of the RuBisCO of this strain may help to implement the Calvin cycle in bacterial chassis of interest such as E. coli .


Usage and Biology

The PRK (phosphoribulokinase or ribulose-5-phosphate kinase) is a phosphotransferase that catalyze the synthesis of RuBP (D-ribulose-1,5-bisphosphate) using ATP and D-ribulose-5-phosphate as a substrate.

This enzyme closes the Calvin cycle by regenerating RuBP, the substrate of the RuBisCO. Its activity plays a key role in directing glucose to the RuBisCO-based pathway. PRK expression without RuBisCO may be toxic to cells. This observation is the basis for phenotypic assays to characterize the activity of PRK and/or RuBisCO (when both are introduced into cells) (Parikh et al., Protein Eng Des Sel, 2007).
