The chemical reactions and pathways involving a purine nucleotide, a compound consisting of nucleoside (a purine base linked to a deoxyribose or ribose sugar) esterified with a phosphate group at either the 3' or 5'-hydroxyl group of the sugar.

Catalysis of the endonucleolytic cleavage of DNA to give random double-stranded fragments with terminal 5' or 3' protrusions, driven by ATP hydrolysis. Cleavage is dependent on the presence in the DNA of a specific recognition site. Cleavage may occur hundreds or thousands of base pairs away from the recognition site due to translocation of DNA.

Catalysis of the hydrolysis of ester linkages within deoxyribonucleic acids by creating internal breaks to yield 5'-phosphomonoesters.

Catalysis of endonucleolytic cleavage of DNA in a site-specific manner, resulting in double-strand breaks.

Generation of movement along a single- or double-stranded DNA molecule, driven by ATP hydrolysis.

The chemical reactions and pathways resulting in the formation of phytochromobilin, which involves the oxidative cleavage of heme by a heme oxygenase(HO) to form biliverdin IX alpha.

The chemical reactions and pathways involving phytochromobilin, the linear tetrapyrrole chromophore required for plant phytochrome photoactivity.

The chemical reactions and pathways resulting in the formation of wax, which includes C16 and C18 fatty acids.

The chemical reactions and pathways resulting in the formation of fatty acid derivative.

Catalysis of the endonucleolytic cleavage of DNA to give specific double-stranded fragments with terminal 5'-phosphates and 3' hydroxyls. Cleavage is dependent on the presence in the DNA of a specific recognition site; cleavage occurs at or very near this recognition site.

Catalysis of the reaction: NADH + H+ + trimethylamine-N-oxide = NAD+ + trimethylamine + H2O.

Catalysis of an oxidation-reduction (redox) reaction in which NADH or NADPH acts as a hydrogen or electron donor and reduces a nitrogenous group.

The process in which a relatively unspecialized epidermal cell acquires the specialized features of a trichome cell. An example of this process is found in Arabidopsis thaliana.

Catalysis of the reaction: L-tryptophan + H(2)O = indole + NH(4)(+) + pyruvate.

The division of a chloroplast within a cell to form two or more separate chloroplast compartments. This division occurs independently of mitosis.

The creation of two or more plastids by division of one plastid. A plastid is any member of a family of organelles found in the cytoplasm of plants and some protists, which are membrane-bounded and contain DNA.

Catalysis of the reaction: urea + H2O = CO2 + 2 NH3.

The chemical reactions and pathways resulting in the formation of amylopectin, the (1->4) linked alpha glucose units with alpha-(1->6) linkages.

Catalysis of the formation of new phosphodiester bonds between a pair of short, unique DNA target sequences; occurs through a phosphotyrosyl intermediate in which the target sequence is first cleaved by the nucleophilic attack by a tyrosine in the active site.

Catalysis of the formation of new phosphodiester bonds between a pair of short, unique target DNA sequences.
