Localization of mycobacteral smegmatis adenosine deaminase.

The study was carried out to check the localization of M.smegmatic adenosine deaminase for its metabolic and clinical importance. The separation and washing of the membrane was done by using refrigerated high-speed centrifuge. The high activity was observed in crude extract while low activity in first washing of the membrane but after second washing there was no enzyme activity seen. Culture media also does not show any enzyme activity. Thus M.smegmatic adenosine deaminase may be a cytosolic enzyme and it does not excreted in to the surrounding media.
