It is commonly used as a defined reagent for assay development, binding studies, and analytical controls where consistent protein specifications are required.\u003c\/p\u003e\u003ch2\u003eKey elements and design rationale\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpressed region:\u003c\/strong\u003e 1-343aa.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpression system:\u003c\/strong\u003e E.coli (may influence folding and post-translational modifications).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTag\/format:\u003c\/strong\u003e C-terminal 6xHis-tagged; Liquid or Lyophilized powder.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpected size:\u003c\/strong\u003e 43.9 kDa (as provided).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePurity:\u003c\/strong\u003e Greater than 95% as determined by SDS-PAGE.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eRegion choice, expression system, and tag\/format can influence folding, post-translational modifications, and interaction behavior in downstream assays.\u003c\/p\u003e\u003ch2\u003eBiological background\u003c\/h2\u003e\u003cp\u003eCould be involved in carbon fixation as a component of the Calvin cycle. Catalyzes the oxidative phosphorylation of glyceraldehyde 3-phosphate (G3P) to 1,3-bisphosphoglycerate (BPG) using the cofactor NAD. The first reaction step involves the formation of a hemiacetal intermediate between G3P and a cysteine residue, and this hemiacetal intermediate is then oxidized to a thioester, with concomitant reduction of NAD to NADH. The reduced NADH is then exchanged with the second NAD, and the thioester is attacked by a nucleophilic inorganic phosphate to produce BPG\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDomain- and isoform-aware assay design to improve biological interpretation across model systems.\u003c\/li\u003e\n\u003cli\u003eQuantitative workflows emphasizing calibration standards, spike-in controls, and cross-lot comparability.\u003c\/li\u003e\n\u003cli\u003eIn vitro binding\/kinetics profiling (SPR\/BLI) to connect biochemical interactions with cellular phenotypes.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMeasure gapA enzymatic activity with defined substrates\/cofactors (in vitro assay).\u003c\/li\u003e\n\u003cli\u003eEvaluate inhibitor\/activator effects on gapA activity across a concentration series.\u003c\/li\u003e\n\u003cli\u003eQuantify gapA using calibration standards in plate-based assays (assay development).\u003c\/li\u003e\n\u003cli\u003eProfile binding interactions of gapA by SPR\/BLI (kinetic characterization).\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret results in the context of the biological system, assay format, and any known domain\/isoform constraints for the target.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConsider species- and isoform-specific differences when comparing results across models or homologs.\u003c\/li\u003e\n\u003cli\u003eFor quantitative assays, include appropriate negative controls and matrix-matched spike-in concepts to assess non-specific signal.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProtKB entry (Q5F5Z2) — UniProt: https:\/\/www.uniprot.org\/uniprotkb\/Q5F5Z2 - NCBI Gene search (gapA) — NCBI: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=gapA - PubMed search — NLM: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=gapA - Reactome pathway browser — Reactome: https:\/\/reactome.org\/ - InterPro protein family resource — EMBL-EBI: https:\/\/www.ebi.ac.uk\/interpro\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53059311534445,"sku":"CSB-EP6458NGA-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53059466854765,"sku":"CSB-EP6458NGA-100UG","price":578.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53059466887533,"sku":"CSB-EP6458NGA-20UG","price":306.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP6458NGA-SDS.jpg?v=1772280383","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-neisseria-gonorrhoeae-glyceraldehyde-3-phosphate-dehydrogenase-gapa-bhp10516224","provider":"BioHippo","version":"1.0","type":"link"}
