Did you know?
PMI has several contributions to necessary metabolic pathways. It enables cells to transform M6P into F6P, which can then be entered into Glycolysis. PMI also allows cells to convert F6P into M6P, which is a common glycolytic cellular identifier for cellular transport and cell membrane identification in prokaryotic and eukaryotic organisms. Webprecise techniques for studying cellular metabolism have been developed. Empowered by these developments, the focus of metabolic engineers has gradually shifted away from …
