Any process that activates or increases the rate, frequency or extent of ligase activity, the catalysis of the ligation of two substances with concomitant breaking of a diphosphate linkage, usually in a nucleoside triphosphate.

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 cyclodiene stimulus. A cyclodiene is any organic insecticide (as dieldrin or chlordane) with a chlorinated methylene group forming a bridge across a 6-membered carbon ring.

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 an organophosphorus stimulus. Organophosphorus is a compound containing phosphorus bound to an organic molecule; several organophosphorus compounds are used as insecticides, and they are highly toxic cholinesterase inhibitors.

positive regulation of oxidoreductase activity

Any process that activates or increases the rate, frequency or extent of oxidoreductase activity, the catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered.

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 pyrethroid stimulus. Pyrethroids are a group of growth regulators, analogous to insect juvenile hormones, that interfere with the development of insect larvae and are used in the control of insects that are harmful in the adult stage.

negative regulation of oxidoreductase activity

Any process that stops or reduces the rate of oxidoreductase activity, the catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered.

Catalysis of the release of an N-terminal tripeptide from a polypeptide; requires acid pH.

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 an arsenic stimulus from compounds containing arsenic, including arsenates, arsenites, and arsenides.
