sequence DNA sequencing of the expression clone for this protein indicated 17 amino acid ...sequence DNA sequencing of the expression clone for this protein indicated 17 amino acid substitutions among the 184 residues in protein Q6FF54 as inferred from the genome sequence of Acinetobacter sp.. The electron density at each of these sites was consistent with the sequence of the expression plasmid and in most cases clearly inconsistent with the reported genome sequence. Authors assume that these differences arise from sequence variations among Acinetobacter strains but have not pursued additional experimental investigations of their origin.
