Pyridoxine/pyridoxamine 5′‐phosphate oxidase (Sgll/PNPO)is important for DNA integrity and glucose homeostasis maintenance in Drosophila
Pyridoxine/pyridoxamine 5′‐phosphate oxidase (PNPO) and pyridoxal kinase (PDXK)
cooperate to produce pyridoxal 5′‐phosphate (PLP), the active form of vitamin B6. PDXK
phosphorylates pyridoxine, pyridoxamine, and pyridoxal by producing PNP, PMP, and PLP,
whereas PNPO oxidizes PNP, PMP, into PLP. We previously demonstrated that PDXK
depletion in Drosophila and human cells impacts on glucose metabolism and DNA integrity.
Here we characterized sgll, the Drosophila ortholog of PNPO gene, showing that its silencing
