Imported muropeptides must contain the disaccharide GlcNAc-anhMurNAc, which is also efficiently transported without attached peptides. Mutants accumulate GlcNAc-anhMurNAc-tripeptide. Transport inhibited by CCCP. 14 TM helices are [predicted, but fusion studies indicate that predicted hydrophobic helices 5, 6, 11, and 12 are in cytoplasmic loops; AmpG probably has 10 TM helices with N-in, C-in topology.
