Part:BBa_K1692020

S. aureus type II PanK (CoaA)

This basic part is a type II pantothenate kinase (panK) from Staphylococcus aureus. Pantothenate kinase is the enzyme that catalyzes the first step in the conversion from pantothenic acid to coenzyme A, and it controls the rate of the pathway because most bacterial panKs experience feedback from coenzyme A or its thioesters [1]. However, this panK is not sensitive to feedback inhibition from coenzyme A or acetyl-CoA, meaning that high levels of coenzyme A accumulate [2]. We did not experiment with this gene alone; instead, we incorporated it into an already-existing BioBrick (BBa_K1149051) to increase the production of poly-3-hydroxybuterate, a plastic of which coenzyme A is a precursor. Our composite part (BBa_K1692021) can explain more about our success with using Pank to increase synthesis of PHA.
