Metabolite Identification
Common NameD-arabinitol 1-phosphate
DescriptionD-arabinitol 1-phosphate is a sugar phosphate belonging to the class of carbohydrate metabolites. Its chemical structure features a phosphate group attached to the D-arabinitol backbone, which is involved in various metabolic pathways, particularly in plant physiology. D-arabinitol 1-phosphate is known for its role in the regulation of Rubisco, a key enzyme in the photosynthetic process. It acts as a precursor to 2-carboxy-D-arabinitol 1-phosphate (CA1P), a potent nocturnal inhibitor of Rubisco that accumulates in plants during periods of darkness or low light, progressively binding to the enzyme and modulating its activity (PMID:36173669 ). This compound, along with other metabolites such as 2-phosphoglyceric acid, demonstrates significant inhibitory effects on Rubisco with sub-nanomolar affinities (PMID:35661591 ). The regulation of Rubisco by CA1P is further highlighted by studies indicating the role of CA1P phosphatase in this regulatory mechanism, suggesting a broader involvement of D-arabinitol 1-phosphate in plant metabolic pathways (PMID:22132794 ).
