Abstract
A fusion chimeric protein is described herein that can assemble a functional carboxysome core, which is able to fix carbon by taking atmospheric carbon dioxide and converting it into useful carbon-containing compounds such as 3-phosphoglycerate (3-PGA).
Claims3
A fusion protein comprising a polypeptide comprising at least two fused small subunit-like domains (SSLDs) that can bind or nucleate with ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), each SSLD comprising at least 95% sequence identity to any of SEQ ID NO:
- 75, 76 or 77, one SSLD fused to at least one domain having carbonic anhydrase activity, and at least one encapsulation peptide that interacts or binds with to one or more carboxysome shell protein, each encapsulation peptide comprising at least 95% sequence identity to any of SEQ ID NO:
- 14, 15 or 16 fused to the at least one carbonic anhydrase domain.
