'''Aminoglycoside 2'-N-acetyltransferase from Mycobacterium tuberculosis-Complex with Coenzyme A and Tobramycin'''
== Function ==
 
[https://www.uniprot.org/uniprot/AAC2_MYCTU AAC2_MYCTU] Catalyzes the coenzyme A-dependent acetylation of the 2' hydroxyl or amino group of a broad spectrum of aminoglycosides. It confers resistance to aminoglycosides.

==Overview==
[[Image:Consurf_key_small.gif|200px|right]]
AAC(2')-Ic catalyzes the coenzyme A (CoA)-dependent acetylation of the 2' hydroxyl or amino group of a broad spectrum of aminoglycosides. The crystal structure of the AAC(2')-Ic from Mycobacterium tuberculosis has been determined in the apo enzyme form and in ternary complexes with CoA and either tobramycin, kanamycin A or ribostamycin, representing the first structures of an aminoglycoside acetyltransferase bound to a drug. The overall fold of AAC(2')-Ic places it in the GCN5-related N-acetyltransferase (GNAT) superfamily. Although the physiological function of AAC(2')-Ic is uncertain, a structural analysis of these high-affinity aminoglycoside complexes suggests that the enzyme may acetylate a key biosynthetic intermediate of mycothiol, the major reducing agent in mycobacteria, and participate in the regulation of cellular redox potential.
