A new family of integral membrane proteins involved in transport of aromatic amino acids in Escherichia coli.
The nucleotide sequence of tnaB of the tryptophanase operon of Escherichia coli is presented. TnaB is a tryptophan-specific permease that is homologous to Mtr, a second tryptophan-specific permease, and to TyrP, a tyrosine-specific permease. Each member of this family appears to contain 11 membrane-spanning domains.
