... degrades InsP6gradually into InsP5, InsP4,and the final product – Ins(2,4,6)P3and Ins(1,3,5)P3–via two alternative pathways [14].Bacterial BPPs containing two tandemly repeateddomains ... functionalrelationship of tandemly repeated domains in BPPs. We conjecture thatdual-domain BPPs have succeeded evolutionarily because they can increasethe amount of available phosphate by interacting together. ... Additionally,fusing PhyH-DI to a single-domain phytase appears to be an efficient way to improve the activity of the latter.IntroductionPhytate (myo-inositol-1,2,3,4,5,6-hexakisphosphate, InsP6)is...
