The genes that encode the universal stress protein (USP) family domain (pfam00582) aid survival of bacteria in specific host or habitat-induced conditions. Genome sequencing revealed genome Helicobacter pylori, a gastric cancer pathogen, typically contains one USP gene, while related helicobacters have two distinct genes. However, insights into functions Helicobacteraceae (Helicobacter and Wolinella) are still limited to inferences from large-scale sequencing. Thus, we combined...
