Catalysis of the reaction: L-valine + H(+) = 2-methylpropanamine + CO(2).

Catalysis of the reaction: L-valine + H2O + NADP+ = 3-methyl-2-oxobutanoate + NH3 + NADPH.

Catalysis of the reaction: (R)-vicianin + H(2)O = mandelonitrile + vicianose.

Catalysis of the reaction: vinylacetyl-CoA = (2E)-butenoyl-CoA.

Catalysis of the reaction: a wax ester + H2O = a long-chain alcohol + a long-chain carboxylate.

Catalysis of the reaction: 5,12-dihydroxanthommatin + NAD(+) = H(+) + NADH + xanthommatin.

Excision from the chromosome and circularization of a region of chromosomal DNA, generally, but not always, via homologous recombination between direct tandem repeats.

Replication of circular DNA following excision from the chromosome; replication of extrachromosomal circular DNA generally occurs independently of chromosomal replication.

OBSOLETE. A process of general metabolic decline that arises in non-dividing cells as they age, and alters cellular metabolism to cause a decline in cell function.

OBSOLETE. 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.) occurring in non-dividing cells as they age as a result of oxidative stress, where the change varies according to the age of the cell or organism.

OBSOLETE. 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.) occurring in dividing cells as they age as a result of oxidative stress, where the change varies according to the age of the cell or organism.

OBSOLETE. 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.) occurring in non-dividing cells as they age as a result of reactive oxygen species, where the change varies according to the age of the cell or organism.

OBSOLETE. Chemical reaction, between proteins and reactive oxygen species, that occurs in dividing cells as they age and leads to a variety of changes in the affected proteins, including increases in protein carbonyl content, oxidized methionine, protein hydrophobicity, and cross-linking.

OBSOLETE. A protein localization process in which progeny cells acquire, or are barred from acquiring, proteins that have been altered by reaction with reactive oxygen species in dividing aging cells.

OBSOLETE. 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.) occurring during the process of replicative cell aging as a result of reactive oxygen species, where the change varies according to the age of the cell or organism.

OBSOLETE. Accumulation of proteins that have undergone reactions with reactive oxygen species in aging dividing cells and exhibit modifications such as increased protein carbonyl content, oxidized methionine, protein hydrophobicity, and cross-linking.

OBSOLETE. Replication of circular DNA following excision from the chromosome of dividing cells as they age; replication of extrachromosomal circular DNA generally occurs independently of chromosomal replication.

OBSOLETE. 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 reactive oxygen species, where the change varies according to the age of the cell or organism.

OBSOLETE. Replication of rDNA following its excision from the chromosome of dividing cells as they age. Extrachromosomal rDNA forms a circle that contains at least one autonomously replicating sequence (ARS), which supports replication independent of chromosomal replication.
