Q: on chloramphenicol resistance genes

[Zophonias Oddur Jonsson]

A fellow lab rat of mine has a question but no answer.  I could not help him
on this one but told him that the net would be the best place to ask
so here we go...

  Chloramphenicol resistance genes (CAT) from R-plasmids in Gram neg.
bacteria are termed type I, II and III according to Shaw (Methods in 
Enzymology 57 pp 754).
  Do you know to which group the CAT-gene of the transposon Tn9 (the same 
as in pBR328) belongs?
