Evidence for arylamine N-acetyltransferase activity in Klebsiella pneumoniae.

Arylamine N-acetyltransferase (NAT) enzymes have been found in laboratory animals, humans, microorganisms (fungi, bacteria and parasites), and in plants. But the characteristics of NAT from Klebsiella pneumoniae are not clear. NAT activities with p-aminobenzoic acid (PABA) and 2-aminofluorene (AF) as substrates were examined in the cytosol of K.
