We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Leadzyme was discovered by Uhlenbeck and co-worked in 1992. The discovery was by in vitro selection, which allows for an isolation and amplification of selected functional molecules. This method has been key in the discovery of numerous RNA and DNA catalysis. Leadzyme, or lead-dependent ribozyme, is among the smallest known catalytic RNAs.

Leadzyme is a relatively small catalytic RNA. In the presence of Pb^2+, it catalyzes the cleavage of the C6-C7 phosphodiester bond <ref>PMID:9813122</ref> . This is accomplished via nucleophilic attack <ref>PMID:9813122</ref> . The resulting in a 2', 3'-cyclic phosphate and a 5'-hydroxyl terminus <ref>PMID:9813122</ref> . The first reaction, increases the Pb^2+ cleavage by 1100-fold rate <ref>PMID:9813122</ref> . The resulting products then trigger a second reaction, in which the product opens to a 3' mono-phosphate group <ref>PMID:9813122</ref> .

This Sandbox is Reserved from September 14, 2021, through May 31, 2022, for use in the class Introduction to Biochemistry taught by User:John Means at the University of Rio Grande, Rio Grande, OH, USA. This reservation includes 5 reserved sandboxes (Sandbox Reserved 1590 through Sandbox Reserved 1594).
To get started:
  • Click the edit this page tab at the top. Save the page after each step, then edit it again.
  • Click the 3D button (when editing, above the wikitext box) to insert Jmol.
  • show the Scene authoring tools, create a molecular scene, and save it. Copy the green link into the page.
  • Add a description of your scene. Use the buttons above the wikitext box for bold, italics, links, headlines, etc.

More help: Help:Editing. For an example of a student Proteopedia page, please see Photosystem II, Tetanospasmin, or Guanine riboswitch.
