CC

mitochondrion

A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.

GO:0009507

CC

chloroplast

A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.

GO:0009570

CC

chloroplast stroma

The space enclosed by the double membrane of a chloroplast but excluding the thylakoid space. It contains DNA, ribosomes and some temporary products of photosynthesis.

GO:0010167

BP

response to nitrate

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a nitrate stimulus.

GO:0016020

CC

membrane

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

GO:0020037

MF

heme binding

Interacting selectively and non-covalently with heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring.

GO:0042128

BP

nitrate assimilation

The nitrogen metabolic process that encompasses the uptake of nitrate from the environment and reduction to ammonia, and results in the incorporation of nitrogen derived from nitrate into cellular substances.

GO:0046872

MF

metal ion binding

Interacting selectively and non-covalently with any metal ion.

GO:0047889

MF

ferredoxin-nitrate reductase activity

Catalysis of the reaction: nitrite + H2O + 2 oxidized ferredoxin = nitrate + 2 reduced ferredoxin.

GO:0048046

CC

apoplast

The cell membranes and intracellular regions in a plant are connected through plasmodesmata, and plants may be described as having two major compartments: the living symplast and the non-living apoplast. The apoplast is external to the plasma membrane and

GO:0048307

MF

ferredoxin-nitrite reductase activity

Catalysis of the reaction: NH3 + 2 H2O + 6 oxidized ferredoxin = nitrite + 6 reduced ferredoxin + 7 H+.

GO:0050421

MF

nitrite reductase (NO-forming) activity

Catalysis of the reaction: nitric oxide + H2O + ferricytochrome c = nitrite + ferrocytochrome c + 2 H+.

GO:0051539

MF

4 iron, 4 sulfur cluster binding

Interacting selectively and non-covalently with a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands.

GO:0055114

BP

oxidation-reduction process

A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
