Dihydroxyacetone phosphate (DHAP, also glycerone phosphate in older texts) is a biochemical compound involved in many metabolic pathways, including the Calvin cycle in plants and glycolysis.

Role in glycolysis[edit]

Dihydroxyacetone phosphate lies in the glycolysis metabolic pathway, and is one of the two products of breakdown of fructose 1,6-bisphosphate, along with glyceraldehyde 3-phosphate. It is rapidly and reversibly isomerised to glyceraldehyde 3-phosphate.

Role in other pathways[edit]

In the Calvin cycle, DHAP is one of the products of the sixfold reduction of 1,3-bisphosphoglycerate by NADPH. It is also used in the synthesis of sedoheptulose 1,7-bisphosphate and fructose 1,6-bisphosphate, both of which are used to reform ribulose 5-phosphate, the 'key' carbohydrate of the Calvin cycle.

DHAP is also the product of the dehydrogenation of L-glycerol-3-phosphate, which is part of the entry of glycerol (sourced from triglycerides) into the glycolytic pathway. Conversely, reduction of glycolysis-derived DHAP to L-glycerol-3-phosphate provides adipose cells with the activated glycerol backbone they require to synthesize new triglycerides. Both reactions are catalyzed by the enzyme glycerol 3-phosphate dehydrogenase with NAD⁺/NADH as cofactor.

DHAP also has a role in the ether-lipid biosynthesis process in the protozoan parasite Leishmania mexicana.

Structural and Functional Analysis of Fucose-Processing Enzymes from Streptococcus pneumoniae.

Higgins MA1, Suits MD1, Marsters C1, Boraston AB2.Author information 1Department of Biochemistry and Microbiology, University of Victoria, PO Box 3055 STN CSC, Victoria, BC, V8W 3P6, Canada.2Department of Biochemistry and Microbiology, University of Victoria, PO Box 3055 STN CSC, Victoria, BC, V8W 3P6, Canada. Electronic address: boraston@uvic.ca.AbstractFucose metabolism pathways are present in many bacterial species and typically contain the central fucose-processing enzymes fucose isomerase (FcsI), fuculose kinase (FcsK), and fuculose-1-phosphate aldolase (FcsA). Fucose initially undergoes isomerization by FcsI producing fuculose, which is then phosphorylated by FcsK. FcsA cleaves the fuculose-1-phosphate product into lactaldehyde and dihydroxyacetone phosphate, which can be incorporated into central metabolism allowing the bacterium to use fucose as an energy source. Streptococcus pneumoniae has fucose-processing operons containing homologs of FcsI, FcsK, and FcsA; however, this bacterium appears unable to utilize fucose as an energy source. To investigate this contradiction, we performed biochemical and structural studies of the S. pneumoniae fucose-processing enzymes SpFcsI, SpFcsK, and SpFcsA. These enzymes are demonstrated to act in a sequential manner to ultimately produce dihydroxyacetone phosphate and have structural features entirely consistent with their observed biochemical activities. Analogous to the regulation of the Escherichia coli fucose utilization operon, fuculose-1-phosphate appears to act as an inducing molecule for activation of the S. pneumoniae fucose operon. Despite our evidence that S. pneumoniae appears to have the appropriate regulatory and biochemical machinery for fucose metabolism, we confirmed the inability of the S. pneumoniae TIGR4 strain to grow on fucose or on the H-disaccharide, which is the probable substrate of the transporter for the pathway. On the basis of these observations, we postulate that the S. pneumoniae fucose-processing pathway has a non-metabolic role in the interaction of this bacterium with its human host.

A comparative study on phosphotransferase activity of acid phosphatases from Raoultella planticola and Enterobacter aerogenes on nucleosides, sugars, and related compounds.

Médici R1, Garaycoechea JI, Valino AL, Pereira CA, Lewkowicz ES, Iribarren AM.Author information 1Laboratorio de Biocatálisis y Biotransformaciones, Universidad Nacional de Quilmes, R.S. Peña 352. Bernal (1876), Buenos Aires, Argentina.AbstractNatural and modified nucleoside-5'-monophosphates and their precursors are valuable compounds widely used in biochemical studies. Bacterial nonspecific acid phosphatases (NSAPs) are a group of enzymes involved in the hydrolysis of phosphoester bonds, and some of them exhibit phosphotransferase activity. NSAP containing Enterobacter aerogenes and Raoultella planticola whole cells were evaluated in the phosphorylation of a wide range of nucleosides and nucleoside precursors using pyrophosphate as phosphate donor. To increase the productivity of the process, we developed two genetically modified strains of Escherichia coli which overexpressed NSAPs of E. aerogenes and R. planticola. These new recombinant microorganisms (E. coli BL21 pET22b-phoEa and E. coli BL21 pET22b-phoRp) showed higher activity than the corresponding wild-type strains. Reductions in the reaction times from 21 h to 60 min, from 4 h to 15 min, and from 24 h to 40 min in cases of dihydroxyacetone, inosine, and fludarabine, respectively, were obtained.

The effect of CO2 on anaerobic succinate production by Corynebacterium glutamicum: carbon flux analysis by 13C-NMR.

Rado X0161 DX1, Turner DL, Fonseca LL, Carvalho AL, Blombach B, Eikmanns B, Neves AR, Santos H.Author information 1Instituto de Tecnologia Química e Biológica, Universidade Nova de Lisboa, Av. da República - EAN, 2780-157 Oeiras, Portugal.AbstractCorynebacterium glutamicum wild type produces a mixture of lactic, succinic and acetic acid from glucose under oxygen deprivation. We investigated the effect of CO2 on the production of organic acids in a two-stage process: cells were grown aerobically in glucose and, subsequently, organic acid production by non-growing cells was studied under anaerobic conditions. The presence of CO2 caused an up to 3-fold increase in the succinate yield (1 mol per mol of glucose), and about 2-fold increase in acetate, both at the expense of L-lactate production; moreover, dihydroxyacetone formation was abolished. The redistribution of carbon fluxes in response to CO2 was estimated by using 13C-labelled glucose and 13C-NMR analysis of the labelling patterns in end-products. The flux analysis showed that 97% succinate was produced via the reductive part of the tricarboxylic acid cycle, the low activity of the oxidative branch being sufficient to provide the reducing equivalents needed for the redox balance. The flux via the pentose phosphate pathway was low (∼5%) regardless of the presence or absence of CO2. Moreover, there was a significant channelling of carbon to storage compounds (glycogen, trehalose), and concomitant catabolism of these reserves. The intracellular and extracellular pools of lactate and succinate were measured by in vivo-NMR and the stoichiometry (H+:organic acid) of the respective exporters was calculated. This study shows that it is feasible to take advantage of natural cellular regulation mechanisms to obtain high yields of succinate with C. glutamicum without genetic manipulation.
