HBV polymerase deduced amino acid (aa) alignment. Comparison of aa sequences of OBI samples with chronic HBV consensus sequence subgenotype F3 reported in GenBank. Substitutions were identified on RT polymerase domain (aa rt107-rt195). The aa were presented in single letter code. The lines indicate the regions of the sequences not included in the analysis. SueroCntP 11 corresponds to the positive control. At the top of the alignment, it is represented by rectangles the ORF P and their domains between aa 1 to 845. Red arrows indicate the A to G motives describe in the HBV polymerase.
