Protein attributes

Sequence length	290 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Participates in the detoxification of a plethora of hydrazine and arylamine drugs. 2-aminofluorene and p-aminobenzoic acid (PABA) are preferred substrates for NAT-2. Less activity with anisidine and barely detectable with SMZ.
Catalytic activity	Acetyl-CoA + an arylamine = CoA + an N-acetylarylamine.
Subcellular location	Cytoplasm.
Polymorphism	There are two forms of NAT2: a rapid/stable Asn-99) and a slow/unstable Ile-99).
Sequence similarities	Belongs to the arylamine N-acetyltransferase family.
