All were born prematurely, as were two of four patients of Hoffman and colleagues (2007) for whom this information was provided. What is pyridoxal phosphate derived from? Pyridoxamine 5-phosphate oxidase (PNPO) deficiency results in a block in the final step of producing pyridoxal 5'- phosphate. This is expected to result in neuronal cell dysfunction that leads to the early neonatal encephalopathy and intractable seizures that are theorized to be resistant to pyridoxine and responsive to pyridoxal 5'-phosphate. Pyridoxal 5'-phosphate (PLP) is formed from vitamin B6 by the action of pyridoxal kinase. These are all important compounds involved in numerous biological functions. Vitamin B6 has several derivatives, including pyridoxal, pyridoxal 5-phosphate (p5p) and pyridoxamine. Severe neurological disorders, such as convulsions and epileptic encephalopathy, result from a reduced availability of pyridoxal 5'-phosphate in the cell, due to inborn errors in the enzymes of the. As described in the accompanying commentary by Gospe . Pyrrole disorder has been long recognized as a significant factor in mental illness and behavior disorders (11).

The dotted lines represent the lower limits of the nonpregnant reference range, as defined by SRL Inc. Tokyo, Japan . Estimated Number of People with this Disease Pyridoxal 5-phosphate (PLP) is the required co-factor for the catalytic activity of approximately one hundred enzymes in the human body, including enzymes involved in the production and degradation of the neurotransmitters glutamate, GABA, glycine, d-serine, dopamine, serotonin and noradrenaline.Consequently, optimal functioning of the nervous system is reliant on an adequate supply of PLP . PLP is also a required cofactor for dopamine synthesis by L-aromatic decarboxylase (L-AADC). Pyridoxal 5-phosphate is the form of B6 the body actually uses. Vitamin B 6 is the generic name for pyridoxine (PN), pyridoxal (PL), pyridoxamine (PM), and their 5-phosphorylated forms: pyridoxine 5-phosphate (PNP), pyridoxal 5-phosphate (PLP), and pyridoxamine 5-phosphate (PMP) (Figure 1).PLP is biologically active and is used as a cofactor in various enzymes where it functions as a so called "electron sink" by condensing with the amino group . Pyrrole disorder aka pyroluria is a type of porphyrin disorder of heme metabolism, whereby elevated hydroxyhemopyrrolin, 2,1 leads to an irreversible binding to B-6 and zinc causing deficiency.
