Sequence and Apoptotic Activity of VacA Cytotoxin Cloned from a Helicobacter pylori Thai Clinical Isolate
Figure 1
Partial nucleotide sequence and deduced amino acid sequence in the m region of recombinant vacA toxin gene from Thai isolate (rVacA) aligned with sequences of H. pylori model strain 60190 (s1/m1) and strain 95-54 (s1/m2). (a) Nucleotide sequences identical in the 3 strains are in blue, and nucleotide sequences identical between 2 strains are shown in yellow. The black box shows the insertion in the middle region of the Thai isolate vacA gene. (b) Amino acid sequences identical in the 3 strains are in blue, and amino acid sequences identical between 2 strains are shown in yellow. The black box shows the insertion in the middle region of the Thai isolate vacA gene.
