Part:BBa_K1807002
Escherichia coli Polyphosphate Kinase Enzyme
This part is a protein coding device containing the Polyphosphate Kinase (PPK) gene from Escherichia coli. PPK produces polyphosphate, more specifically PPK catalyzes the reversible conversion of the γ-phosphate of ATP to the end of the polyphosphate chain (Akiyama et al., 1992). This enzyme is responsible for the formation of long chain polyphosphate molecules (up to a thousand orthophosphate residues long) - see illustration below.
