Abstract: A method for the one-pot production of geranylgeranylated proteins in Escherichia coli. E. coli is engineered to express geranylgeranyl pyrophosphate synthase, an enzyme that catalyzes production of geranylgeranyl pyrophosphate, and a target protein. By co-expressing GGS with a geranylgeranyltransferase, efficient geranylgeranylation of model protein substrates was achieved, including intrinsically disordered elastin-like polypeptides (ELPs) and the globular protein mCherry. This modification af[...]
Our summary: A one-pot method for producing geranylgeranylated proteins in E. coli was developed. The method involves co-expressing geranylgeranyl pyrophosphate synthase and geranylgeranyltransferase for efficient modification of target proteins.
