Activating Compound

EC Number Activating Compound Comment Organism Structure
7.1.2.2 2,4-dinitrophenol plant hormone 2,4-dinitrophenol does not influence enzyme expression, but highly increases the enzyme's H+-translocation activity Hordeum vulgare
7.1.2.2 abscisic acid plant hormone abscisic acid slightly induces the enzyme expression and highly increases the enzyme's H+-translocation activity Hordeum vulgare
7.1.3.1 2,4-dinitrophenol 2,4-dinitrophenol increases the expression of HVP1, treatment with abscisic acid and 2,4-dinitrophenol increases Na+/H+ antiport activity and proton translocating activities by H+-PPase and H+-ATPase in tonoplast vesicles, and treatment with abscisic acid also increases the amount of V-PPase protein of tonoplast vesicles, overview Hordeum vulgare
7.1.3.1 abscisic acid abscisic acid markedly induces the expression of HVP1 and slightly increased the expression of HVP10, treatment with abscisic acid and 2,4-dinitrophenol increases Na+/H+ antiport activity and proton translocating activities by H+-PPase and H+-ATPase in tonoplast vesicles, and treatment with abscisic acid also increases the amount of V-PPase protein of tonoplast vesicles, overview Hordeum vulgare
7.1.3.1 additional information HVP1 transcripts also increase 5 h after treatment with another synthetic auxin, 1-naphthaleneacetic acid, and native auxin, 3-indoleacetic acid, while the level of HVP10 transcript does not increase after treatment with the two auxins, no effect on gene expression by gibberellic acid, salt stress increases the levels of HVP and HVP10 transcripts in the roots of barley seedlings, osmotic stress also increases the levels of HVP1 transcripts in the roots Hordeum vulgare

7.1.2.2 ATP + H2O + H+/in Hordeum vulgare enzyme regulation, especially under salt stress, involving plant hormones, overview. Under salt stress, the accelerated extrusion and vacuolar compartmentalization of Na+ from the cytoplasm by the Na+/H+ antiporter cause lower pH in the cytoplasm, and V-PPase, EC 3.6.1.1, activity might complement the V-ATPase activity increased by the pH change, overview ADP + phosphate + H+/out
