Design Notes

The part is designed to produce a fusion protein of the codon-optimized plant-growth promoting enzyme 1-aminocyclopropane-1-carboxylate deaminase (ACCD) and enhanced green fluorescent protein (eGFP or GFPmut3b). Organisms which express ACCD have been implicating in promoting resilience to osmotic stresses such as drought and soil salinization. The attachment of the eGFP domain by a flexible linker allows for visualization of bacteria carrying the plasmid in plant tissues. It also improves ability to select transformed colonies in bacterial strains with high number of non-transformed colonies. There is a His tag for optional purification of the protein.

Source

The amino acid sequence of acdS comes from isolated endophytic bacteria Pseudomonas sp. 1C2P-04, and primers for its amplification were based on Pseudomonas sp. UW4 [1]. The promoter, RBS, eGFP with His-tag, and terminator are derived from pJK_proB_eGFP (Bienick et al. 2014).
