Figure 3From: Genetic microheterogeneity and phenotypic variation of Helicobacter pylori arginase in clinical isolatesH. pylori prevents arginase activity from becoming too elevated. Wild type H. pylori strain SS1 was transformed with the rocF mutation (rocF), a vector control inserted into the intergenic hp0203-0204 site (203C04), or with the intergenic plasmid carrying the wild type rocF coding region and native promoter (MLB004).Back to article page
