Category:Enzymes of unknown structure
Wikimedia Commons has media related to Enzymes of unknown structure.
This category assembles enzymes for which there is no known atomic-resolution structure. However, these entries were current as of October 2007, but new structures are always being determined; if you should see an error here, please correct it by moving the enzyme to Category:Enzymes of known structure.
