- nor-spermidine metabolic process
The chemical reactions and pathways involving nor-spermidine, a compound related to spermidine, N-(3-aminopropyl)-1,4-diaminobutane.
- nor-spermidine catabolic process
The chemical reactions and pathways resulting in the breakdown of nor-spermidine, a compound related to spermidine, N-(3-aminopropyl)-1,4-diaminobutane.
- nor-spermidine biosynthetic process
The chemical reactions and pathways resulting in the formation of nor-spermidine, a compound related to spermidine, N-(3-aminopropyl)-1,4-diaminobutane.
- obsolete dipeptidase E activity
OBSOLETE. Catalysis of the hydrolysis of dipeptides Asp-Xaa; does not act on peptides with N-terminal Glu, Asn or Gln, nor does it cleave isoaspartyl peptides.
- DNA-(abasic site) binding
Binding to a DNA site that has neither a purine nor a pyrimidine base. Apurinic sites can form spontaneously or when DNA glycosylase removes a damaged base.
- obsolete dipeptidyl-peptidase IV activity
OBSOLETE. Catalysis of the release of an N-terminal dipeptide, by the hydrolysis of the Xbb-Xcc bond in Xaa-Xbb-Xcc, preferentially when Xbb is Pro, provided Xcc is neither Pro nor hydroxyproline.
- obsolete peptidyl-dipeptidase A activity
OBSOLETE. Catalysis of the release of a C-terminal dipeptide, Xaa-Xbb from oligopeptide-Xaa-Xbb, when Xaa is not Pro, and Xbb is neither Asp nor Glu. Converts angiotensin I to angiotensin II.
- aerobic respiration, using nitrite as electron donor
The oxidation of nitrite (NO2) to nitrate (NO3), using oxygen (O2) as the electron acceptor. Nitrite oxidation is the final step in nitrification, the oxidation of ammonia to nitrate, and nitrite oxidoreductase (NOR) is the key enzyme complex that catalyzes the conversion of nitrite to nitrate in nitrite oxidizing species.
