Peptidyl-tRNA+hydrolase

=**Target (protein/gene name): Peptidyl-tRNA hydrolase**=


 * NCBI Gene # :** 16202917


 * Protein ID (NP or XP #):** MASS_1138


 * Organism (including strain):** //Mycobacterium abscessus// (strain: 50594)


 * Etiologic Risk Group (see link below):** Risk Group 2 (WHO classification)

//Mycobacterium abscessus// is related to the bacterium that cause tuberculosis. Commonly found in the environment like water and soil, it can easily contaminate objects such as medical equipment. Transmission usually occurs due to injections of contaminated substances or contact with contaminated equipment. The bacterium can then enter the human body, causing an infection. The symptoms that manifest once //Mycobacterium abscessus// infection takes place includes red, swollen skin. Fevers, chills, and general malaise are all signs of possible infection. Chronic lung disease can also originate from this bacterium infection, especially if the victim has a weak immune system. To treat the infection, the pus or infected tissue is first removed, then various antibiotics can be taken for a period of time.

Peptidyl-tRNA hydrolase (PTH) is a protein that cleaves the bond between the peptide and tRNA during premature release of tRNA from the ribosome. This is significant in that the bacterium will have a supply of tRNA to use for the next translation. No tRNA will be wasted if a translation process is aborted halfway through. Overall, this enzyme is vital to cell viability. Inhibition of this enzyme will cripple the supply of tRNA //Mycobacterium abscessus// has for synthesizing more proteins, thus effectively reducing viability.
