On October 22-24, 1998, a workshop was held at Kuranda, Queensland, Australia. The purpose of the meeting was to provide a forum for discussion of a number of diverse research areas of the biochemistry and molecular biology of arylamine N-acetyltransferases and to foster collaboration among several major groups of investigators around the world. In addition, participants were asked to consider how the nomenclature system for arylamine N-acetyltransferases could be strengthened to cope with the burgeoning number of new alleles discovered in the last 3 years.
