Lysyl-tRNA synthetase (LysS) is a member of the class II aminoacyl-tRNA synthetases and catalyses the specific aminoacylation of tRNA(Lys). There are two different proteins that code for lysyl-tRNA synthase, LysS and LysU. The LysS is expressed under normal contionds, where the LysU is overexpressed in conditions like high temperature, anaerobiosis, low external pH, or the presence of leucine. <ref>PMID:11041850</ref> The source organism comes from Escherichia coli. The LysS is a protein that plays an important role in the translation of the genetic sequence. The LysS aids in an accurate translation of the mRNA. <ref>PMID:26794499</ref>

A defect in the translation of the genetic material from LysS would impact the functionality of the protein. The LysS gene has been determined to coincide with the HerC gene. Lysyl-tRNA synthase has been thought to be used for a drug target that lead to drug discovery capable of clearing parasites from mouse models with malaria and cryptosporidiosis infection. <ref>PMID:1814685116</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.
