enzyme

== English == === Etymology === From German Enzym, coined 1878 by the German physiologist Wilhelm Kühne from Ancient Greek ἐν (en, “in”) +‎ ζύμη (zúmē, “leaven”). === Pronunciation === IPA(key): /ˈɛn.zaɪm/ Rhymes: -aɪm Hyphenation: en‧zyme === Noun === enzyme (countable and uncountable, plural enzymes) (biochemistry) A biomolecule that catalyses a biological chemical reaction: either a globular protein with this function or an RNA molecule with this function. Hypernym: biocatalyst Hyponym: ribozyme (strictly) The protein type specifically. Hypernym: biocatalyst Hyponym: see list Coordinate term: ribozyme (Christianity) Leavened bread, as opposed to azyme. ==== Usage notes ==== Before 1980, protein enzymes were the only known type, so the word enzyme invariably meant that type. Since RNA catalysis was discovered, ribozymes are often viewed as a type of enzyme (in the newer and broader sense of the word), but even today, their name is often used coordinately with the stricter sense. ==== Derived terms ==== ==== Related terms ==== ==== Translations ==== === Further reading === enzyme on Wikipedia.Wikipedia == French == === Etymology === From Ancient Greek ἐν (en, “in”) +‎ ζύμη (zúmē, “sourdough”). === Noun === enzyme m or f (plural enzymes) (biochemistry) enzyme === Verb === enzyme inflection of enzymer: first/third-person singular present indicative/subjunctive second-person singular imperative === Further reading === “enzyme”, in Trésor de la langue française informatisé [Digitized Treasury of the French Language], 2012
