Real enzymes, rule-built names and sci-fi inventions
Get 1,000 enzyme names in one list: real enzymes such as Amylase, DNA Ligase, Dicer and Sortase A, names built by the standard naming rule like Keratin Hydrolase, and plainly fictional ones like Chronokinase and Homework Hydrolase. The list mixes real and invented names and is not a reference, so check a name in a textbook or database before you cite it.
About enzyme names
Most enzyme names follow one rule: say what the enzyme acts on, say what it does, and end with -ase. Lactase splits lactose, DNA Ligase joins strands of DNA, and Hexokinase adds a phosphate group to six-carbon sugars. A few names are older than the rule and end in -in, such as Pepsin, Trypsin and Papain. Restriction enzymes use a code of their own, built from the bacterium each one was found in: the Eco in EcoRI stands for Escherichia coli.
This list holds 1,000 names of three kinds. About two thirds are real enzymes: digestive and metabolic staples, DNA and RNA machinery, restriction enzymes, and real oddities like Dicer, Flippase, Katanin and Zucchini Endonuclease. A second group is built by the naming rule from familiar substrates, for example Keratin Hydrolase or Vanillinase; a name made the real way may match an enzyme someone has already described. The third group is plainly fictional, with substrates no chemist keeps on a shelf: Chronokinase, Xenolith Hydrolase, Procrastinase.
The page is a source of names, not a reference. Nothing in the list marks which kind a name is, so before you cite one in homework, a paper or a quiz, look it up in a textbook or an enzyme database.
How to choose enzyme names
- To build your own, pick a substrate, pick an action and add -ase. The classic action classes are oxidoreductases, transferases, hydrolases, lyases, isomerases and ligases, with translocases added later as a seventh.
- For a science fiction enzyme, make the substrate impossible (time, starlight, a void crystal) and keep the ending real. Tachyon Polymerase works because only half of it is nonsense.
- For a quiz team or a class project, pick a real name you can explain in one line: Dicer cuts double-stranded RNA into short pieces, and Helicase unwinds the double helix.
- Copy restriction enzymes exactly as written. EcoRI, BamHI and HindIII are codes, so the capitals and the Roman numeral at the end are part of the name.
- Before a name goes into graded work or print, look it up in a textbook or an enzyme database. The list does not tell real names from invented ones.
Frequently asked questions
Are all of these real enzymes?
No. About two thirds are real, including Amylase, Catalase, Telomerase and Carbonic Anhydrase. The rest are either built by the naming rule, like Starch Hydrolase, or plainly fictional, like Voidoxidase and Sock Isomerase. The page is not a reference, so look a name up in a textbook or database before you cite it.
Why do most enzyme names end in -ase?
The ending was borrowed from diastase, one of the first enzymes to be described, and it became the standard suffix for enzymes in the late 1800s. Names that are older than the convention kept their -in ending, which is why Pepsin and Trypsin look different from Lactase and Catalase.
What are some funny real enzyme names?
Dicer, Separase, Sortase A, Flippase, Katanin, Wee1 Kinase and Old Yellow Enzyme are all real and all in the list. So are Zucchini Endonuclease, Nibbler Exoribonuclease and Twinkle Helicase.
Can I use an invented enzyme name in a story or a game?
Yes. The fictional names are made for that: Nanite Polymerase, Dragon Scale Keratinase and Deadline Kinase read as enzymes because they keep the real grammar of substrate, action and -ase. A rule-built name such as Caffeine Demethylase may match an enzyme that has been described, so look it up first if your story needs a name nobody uses.
