Class of compounds, aldimines, derived by chemical reaction (condensation) of aldehydes or ketones with primary amines; the general formula is RR'C = NR". Such compounds may be formed by amino acids during metabolism; some substrates probably form these compounds with an enzyme amino group during an enzymatic reaction. 1, record 1, English, - Schiff%20base

In the lysine class, represented by fructose-diphosphate aldolase, an intermediate Schiff's base is formed between the [epsilon]-amino group of a lysine residue of the enzyme and carbonyl group of the substrate. Many enzymes forming covalent intermediates show the characteristic kinetic behavior of double-displacement, or ping-pong, reactions. 3, record 1, English, - Schiff%20base

Les bases de Schiff sont des composés intermédiaires se formant dans un grand nombre de réactions enzymatiques où un enzyme agit sur une fonction amine ou carboxyle d'un substrat. [...] La catalyse covalente est de règle dans les réactions auxquelles participent les coenzymes : ainsi, le pyridoxal-phosphate participe à la décarboxylation oxydative des acides aminés par l'intermédiaire d'une base de Schiff, aisément mise en évidence par son spectre optique caractéristique. 3, record 1, French, - base%20de%20Schiff
