(a) Alignment of nucleotide sequence of cagA 3' end repeat region of strain PCR 127i and I-230. Predicted amino acid sequence was given at the bottom of the figure and motifs are represented as different colors. A 57 base deletion was observed in strain I-230, which results in loss of 19 amino acids. These 19 amino acids include V1 and an EPIYA motif (Y2). (b) Identification of deletions observed in the repeat region at the C-terminal of CagA of H. pylori strains isolated from India. Each motif was assigned a color and the regions deleted were shown in dashed line.
