Common NameL-histidinol phosphate
DescriptionL-histidinol phosphate is a member of the phosphate esters chemical class, specifically functioning as a metabolic intermediate in the biosynthesis of the amino acid L-histidine. Its chemical structure features a phosphate group esterified to L-histidinol, which is derived from the enzymatic conversion of imidazole acetol phosphate by the enzyme HISN6, a pyridoxal 5'-phosphate-dependent enzyme (PMID:36842242 ). The hydrolysis of L-histidinol phosphate to L-histidinol and inorganic phosphate is catalyzed by histidinol phosphate phosphatase (HPP), marking the penultimate step in the histidine biosynthetic pathway (PMID:23327428 ). This process is crucial for the proper synthesis of histidine, with HPP belonging to the PHP family of proteins, which includes other enzymes involved in nucleotide metabolism (PMID:17929834 ). Additionally, L-histidinol phosphate is a substrate for histidinol phosphate aminotransferase (HisC), which facilitates the seventh step in histidine synthesis, further illustrating its role in metabolic pathways (PMID:11518529 ). Structural studies have provided insights into the mechanisms of enzymes acting on L-histidinol phosphate, enhancing our understanding of its biochemical significance (PMID:30149858 ).
