Transcriptional regulatory protein; NAD-dependent lysine deacetylase and desuccinylase that specifically removes acetyl and succinyl groups on target proteins. Modulates the activities of several proteins which are inactive in their acylated form (By similarity). Reactivates acetylated acetyl-CoA synthetase (ACS) through an NAD-dependent deacetylation. Is able to ADP-ribosylate itself.

Conserved hypothetical protein; May have transcription regulation and metal-detoxifying functions through which it may enhance intracellular survival of mycobacteria. Binds to its own promoter region and to the Rv1999c promoter region. It displays strong affinity for cadmium ions, but can also bind zinc, manganese and nickel. Expression increases the intracellular survival of recombinant M. smegmatis in murine macrophage cell line and increases its tolerance to cadmium ions.
