The phrase "active nitrate" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in chemistry or environmental studies, to refer to nitrate that is readily available for biological uptake or chemical reactions.
Example: "The soil sample showed a high concentration of active nitrate, which is essential for plant growth."
Alternatives: "bioavailable nitrate" or "reactive nitrate".
P. aerophilum Nar is the first active nitrate reductase that contains a W cofactor.
It is not clear how much, if any, ZmNrt2.1 could oligomerize with NtNAR2 to form an active nitrate transporter complex, as suggested for other plants (Tong et al. 2005; Yong et al. 2010; Pii et al. 2016).
For example, in Arabidopsis both the NRT2.1 and NAR2.1 proteins were shown to localize and interact at the plasma membrane in the roots, where the active nitrate transporter is presumably formed as a NRT2.1/NAR2.1 heterooligomer (Wirth et al. 2007; Yong et al. 2010).
In our study we used the strain CC503, a nit1 nit2 mutant lacking an active nitrate signaling pathway (nit2).
An active nitrate reductase in the presence of NO, has been shown to promote M. tuberculosis growth [ 125], to be a source of nitrite (which could then acts as signal molecule for M. tuberculosis) [ 122] or potentially disrupt NO signalled apoptosis [ 126].
Correspondingly, NADP+-ICDH was less active in lower nitrate concentrations than higher (Table 4).
The active sites for nitrate and nitrite hydrogenation over Pd Cu/TiO2 are discussed individually.
Combined experimental and theoretical findings suggest that the superior catalytic performance of SmMn2O5 mullite arises from the ability to regenerate its active sites with nitrate dissociation at lower temperatures for subsequent NO oxidation reactions.
There are a number of hypotheses that could explain this phenomenon: (1) root maintenance respiration rate increased; (2) the alternative respiratory pathway was stimulated; (3) root growth was stimulated; (4) active nutrient uptake and nitrate reduction were enhanced; (5) root exudation and microbial activity in the root zone increased.
Together, the changes in these cyclic nucleotide metabolites suggest active second messenger activity involved in nitrate regulation.
Together, the changes in all these nucleotide metabolites suggest active second messenger activity involved in nitrate regulation.
