		+	== Publication Abstract from PubMed ==
		+	Enhanced intracellular survival (Eis) proteins belonging to the superfamily of the GCN5-related N-acetyltransferases play important functions in mycobacterial pathogenesis. In Mycobacterium tuberculosis, Eis enhances the intracellular survival of the bacilli in macrophages by modulating the host immune response and is capable to chemically modify and inactivate aminoglycosides. In nontuberculous mycobacteria (NTM), Eis shares similar functions. However, Mycobacterium abscessus, a multidrug resistant NTM, possesses two functionally distinct Eis homologues, Eis1Mab and Eis2Mab . While Eis2Mab participates in virulence and aminoglycosides resistance, this is not the case for Eis1Mab, whose exact biological function remains to be determined. Herein, we show that overexpression of Eis1Mab in M. abscessus fails to induce resistance to aminoglycosides. To clarify why Eis1Mab is unable to modify this class of antibiotics, we solved its crystal structure bound to its cofactor, acetyl-CoA. The structure revealed that Eis1Mab has a typical homohexameric Eis-like organization. The structural analysis supported by biochemical approaches demonstrated that while Eis1Mab can acetylate small substrates, its active site is too narrow to accommodate aminoglycosides. Comparison with other Eis structures showed that an extended loop between strands 9 and 10 is blocking the access of large substrates to the active site and movement of helices 4 and 5 reduces the volume of the substrate-binding pocket to these compounds in Eis1Mab . Overall, this study underscores the molecular determinants explaining functional differences between Eis1Mab and Eis2Mab, especially those inherent to their capacity to modify aminoglycosides.
