Lysyl-tRNA Synthetase

Lysyl-tRNA Synthetase has a couple known names, one of them being aminocyl tRNA. The major role of this protein is translation during protein synthesis. For a protein to be classified and placed into an amino acid group, its amino acid sequence must be properly translated. Transfer RNA helps translate the protein which helps with genetics. Aminoacyl tRNA synthetases are the enzymes that are responsible for the specific aminoacylation of tRNA (Yifat, 2013). Let’s take a more in depth look at the function of this protein by breaking it down.
Lysyl, otherwise known as lysyl oxidase, is synthesized as a preproprotein, meaning it contains a nonpolar signal polypeptide sequence. There are 23 preproteins, but our body can only distinguish between 20 of the 23, hence the 20 amino acids our body can distinguish. In the extracellular matrix, lysyl oxidase helps initiate the crosslinking of collagen and elastin. (Ibba, 1997). Lysyl also contributes to fat and stem cells and helps the formation of lysyl-tRNA.
Transfer nucleic acid is another name for tRNA. Transfer RNA’s (tRNA) purpose is to transfer specific amino acids to the polypeptide chain that keeps growing (Yifat, 2013). Messenger RNA (mRNA) gets help from tRNA, which decodes and helps convert the amino acids to a protein. Transfer RNA’s anticodons help take the amino acids off of mRNA and connect it to the end of the amino acid…
