Gibberellic acid 1 Publications Verification Gibberellin A3	Structural Classification Microorganisms Classification of Application Fields Gibberellins Rutaceae Other Diseases Plants Phytohormone Disease Research Fields Citrus reticulata Blanco Agricultural Research	Environmental Pollutants Drug Derivative
Gibberellic acid (GA₃) is a natural plant growth regulator with oral bioactivity. Gibberellic acid governs multiple plant developmental events, including seed germination, cell elongation, floral organ formation, and rice spikelet fertility. Gibberellic acid optimizes root morphology and secondary metabolite production in Echinacea purpurea hairy roots, and serves as a bioactive seed priming agent to improve chilling stress tolerance in chickpea. Gibberellic acid mediates modulation of enzyme activity and secondary metabolism in plants and exerts tissue-specific regulatory effects on antioxidant systems and lipid peroxidation in rats. Gibberellic acid can be used in studies of plant growth, metabolism, and abiotic stress responses .

	APPBP1-UBA3/NEDD8 E1 Protein, Human A-116A10.1; amyloid beta precursor protein binding protein 1; amyloid beta precursor protein binding protein 1, 59kDa; Amyloid beta precursor protein-binding protein 1, 59 kDa; amyloid beta precursor protein-binding protein 1, 59kD; Amyloid protein-binding protein 1; APPBP1APP-BP1; NEDD8 activating enzyme E1 subunit 1; NEDD8-activating enzyme E1 regulatory subunit; NEDD8-activating enzyme E1 subunit; protooncogene protein 1; Proto-oncogene protein 1; ula-1	Human	E. coli
	The APPBP1-UBA3/NEDD8 E1 protein is the regulatory subunit in the UBA3-NAE1 E1 enzyme complex and activates NEDD8 by adenylating its C-terminal glycine with ATP. This forms the NEDD8-UBA3 thioester, which is transferred to the catalytic cysteine of UBE2M. APPBP1-UBA3/NEDD8 E1 Protein, Human is a recombinant protein dimer complex containing human-derived APPBP1-UBA3/NEDD8 E1 protein, expressed by E. coli , with tag free. APPBP1-UBA3/NEDD8 E1 Protein, Human, has molecular weight of 60 kDa (APP-BP1) 50 kDa (UBA3).

	RIPK2 is a multifunctional serine/threonine/tyrosine protein kinase that coordinates innate and adaptive immune responses. It is activated by bacterial peptidoglycan to form filaments in the NOD1 and NOD2 pathways, undergoing autophosphorylation and polyubiquitination. RIPK2 Protein, Human (P. pastoris, His) is the recombinant human-derived RIPK2 protein, expressed by P. pastoris , with C-6His, C-6His labeled tag.
