Dithiothreitol 16-19 MLO-like protein 4 Zea mays 52-83 24458697-2 1984 The inactivation by CuCl2 could be reversed by dithiothreitol, suggesting the involvement of vicinal dithiols in the inactivation process.Complete inactivation of phosphoenolpyruvate carboxylase was correlated with the incorporation of two mol ((3)H)N-ethylmaleimide per 100-kilodalton subunit. Dithiothreitol 47-61 MLO-like protein 4 Zea mays 163-194 16663773-1 1984 Incubation of purified phosphoenolpyruvate carboxylase from Zea mays L. leaves with dithiothreitol resulted in an almost 2-fold increase in the enzymic activity. Dithiothreitol 84-98 MLO-like protein 4 Zea mays 23-54 16663773-3 1984 The activation induced by dithiothreitol was reversed by diamide, an oxidant of vicinal dithiols, suggesting that the redox state of disulfide bonds of the enzyme may be important in the expression of the maximal catalytic activity.Titration of thiol groups before and after activation of maize phosphoenolpyruvate carboxylase by dithiothreitol shows an increase of the accessible groups from 8 to 12 suggesting that the reduction of two disulfide bonds accompanied the activation. Dithiothreitol 26-40 MLO-like protein 4 Zea mays 295-326 16663773-3 1984 The activation induced by dithiothreitol was reversed by diamide, an oxidant of vicinal dithiols, suggesting that the redox state of disulfide bonds of the enzyme may be important in the expression of the maximal catalytic activity.Titration of thiol groups before and after activation of maize phosphoenolpyruvate carboxylase by dithiothreitol shows an increase of the accessible groups from 8 to 12 suggesting that the reduction of two disulfide bonds accompanied the activation. Dithiothreitol 330-344 MLO-like protein 4 Zea mays 295-326 16663773-5 1984 It is concluded that the mechanism of phosphoenolpyruvate carboxylase activation by dithiothreitol involves the net reduction of two disulfide bonds in the enzyme. Dithiothreitol 84-98 MLO-like protein 4 Zea mays 38-69 11773521-3 2001 The purified PEPC-PK was readily inactivated under mild oxidative conditions, but the activity could be recovered by dithiothreitol (DTT). Dithiothreitol 117-131 MLO-like protein 4 Zea mays 13-17 11773521-3 2001 The purified PEPC-PK was readily inactivated under mild oxidative conditions, but the activity could be recovered by dithiothreitol (DTT). Dithiothreitol 133-136 MLO-like protein 4 Zea mays 13-17
