I'm looking for an enzyme that does not function as part of a complex in its active state. Preferably it also is not part of a kinase or other kind of activating cascade as well though I would appreciate any and all names that are not part of a complex in its active state. Also would be better if it does not require post translational modifications. Of course, pre translational modifications/ interactions at rna or dna level are all good. In eukaryotic genome but bonus points for human genome! Thanks!!

$\begingroup$ Ribozymes are made of 2 subunits though. I'm basically wondering if there is a protein with no quaternary structure and maybe even those little things I mentioned above. $\endgroup$– Sarthak GargCommented Sep 10, 2020 at 0:00

$\begingroup$ I'm not really sure how else to phrase unfortunately. But that's a good thing to learn about! Feel free to edit or advise and I'll comply! $\endgroup$– Sarthak GargCommented Sep 10, 2020 at 3:00

2$\begingroup$ I can't really suggest an edit because I have no idea what problem you are trying to solve, and that's kind of the problem with XY questions. What is your goal? $\endgroup$– Bryan Krause ♦Commented Sep 10, 2020 at 3:29

Acetylcholinesterase.
Chosen because the esterase seems like a low energy reaction so it wouldn't need energetic co-factors.

Not sure if I should do a new answer or not.

$\begingroup$ Yeah. The Zn is a cofactor so technically doesn't add to the quaternary structure. I'll keep the question open in case someone identifies a completely isolated enzyme. $\endgroup$ Commented Sep 10, 2020 at 3:02
