It has a potent multisubunit urease enzyme that enables it to survive in acidic pH conditions and colonize the gastric environment (TIGR, 2004). H. pylori utilizes the enzyme urease to convert urea into bicarbonate and ammonia to combat the low acidity of the stomach. The mixing of the two extreme pH levels creates a neutralized protective cloud around the H. pylori , allowing it to survive in the stomach (Helicobacter Foundation, 2004 )
