title: Evolution of transcription-regulating proteins: caveat lector!
abstract: The paper of Hawkins et al. [Gene 146 (1994) 145-158] reports incorrect descriptions of mutant phenotypes, omits mention of the absence of a highly relevant glutamine-binding site and contains sequence alignments which might mislead the reader. Extensive sequence analysis reveals as untenable a central hypothesis of the paper concerning a possible evolutionary relationship between anthranilate synthetases and the transcription factors mediating nitrogen metabolite repression in fungi.
