Characterization of the putative operon containing arylamine N-acetyltransferase (nat) in Mycobacterium bovis BCG

NAT 2 ( N - acetyltransferase 2 ( arylamine N - acetyltransferase ) )

NAT 1 ( N - acetyltransferase 1 ( arylamine N - acetyltransferase ) )

The human NAT1 gene has nine exons. The coding region is located in exon 9 and spans 870 bp. Diverse NAT1 transcripts have been reported and two promoters exist. The first promoter, designated as P1 is located in the 5' flanking region of exon 1 and controls two major (a1 and a2) transcripts. The second promoter is located upstream of exon 4 and give rise to at least five (b1 to b5) different t...

Characterization of the heat shock response in Mycobacterium bovis BCG.

We have for the first time characterized the heat shock response in mycobacteria both at the level of transcription, by RNA extraction, Northern (RNA) blotting, and hybridization with gene-specific probes for the Mycobacterium tuberculosis 65- and 71-kDa heat shock proteins (HSPs), and at the level of translation, by [35S]methionine labelling, sodium dodecyl sulfate-polyacrylamide gel electroph...

Arylamine N-Acetyltransferase Is Required for Synthesis of Mycolic Acids and Complex Lipids in Mycobacterium bovis BCG and Represents a Novel Drug Target

Mycolic acids represent a major component of the unique cell wall of mycobacteria. Mycolic acid biosynthesis is inhibited by isoniazid, a key frontline antitubercular drug that is inactivated by mycobacterial and human arylamine N-acetyltransferase (NAT). We show that an in-frame deletion of Mycobacterium bovis BCG nat results in delayed entry into log phase, altered morphology, altered cell wa...
