Isoleucyl-tRNA synthetase

Definition

Isoleucyl-tRNA synthetase is an enzyme that catalyzes the attachment of the amino acid isoleucine to its corresponding transfer RNA (tRNA) molecule during protein synthesis. This process is crucial for ensuring the accurate translation of genetic information into functional proteins, particularly in the context of dermatologic conditions and topical anti-infectives for burns.

5 Must Know Facts For Your Next Test

1. Isoleucyl-tRNA synthetase is responsible for the specific recognition and attachment of the amino acid isoleucine to its cognate tRNA molecule.
2. Disruption of isoleucyl-tRNA synthetase activity can lead to errors in protein synthesis, which may contribute to the development or exacerbation of certain dermatological conditions.
3. Topical antimicrobial agents that target isoleucyl-tRNA synthetase can be effective in treating bacterial infections, including those that may arise in the context of burns or other skin injuries.
4. Inhibition of isoleucyl-tRNA synthetase is a mechanism of action for some antibacterial drugs, as it can disrupt protein synthesis and lead to cell death in susceptible microorganisms.
5. Monitoring the activity of isoleucyl-tRNA synthetase may be important in assessing the efficacy of certain topical treatments for dermatological conditions or infections associated with burns.
