From: A novel PBP3 substitution in Haemophilus influenzae confers reduced aminopenicillin susceptibility
The amino acid sequence of the transpeptidase domain of PBP3 is shown for the wild-type PBP3 strain NTHi3655 as well as for the mutated strain NTHi3655-PBP3Y528H and the clinical strain NTHi93–57,485 expressing the Y528H substitution. For comparison, the PBP3 sequence of H.influenzae Rd. is also shown (GenBank:U32793). None of the other resistance-associated substitutions listed in Table 1 is present in any of the isolates
