Subunits

Subunits Comment Organism
dimer the homodimer contains an extended C-terminal tail comprising residues 193-213. Dimer interface and domain interface structure analysis: the shortest domain contacts involve residues Phe17, Leu52, Phe53, Tyr71, and Phe75 on one domain and Val145, Pro151, Val154, Tyr173, Phe177, His180, Cys189, Leu198, Ile205, and His210 on the other domain, and the dimer interface is stabilized by 10 hydrogen bonds and approximately 102 non-bonded contacts, involving 32 residues from both chains, overview Helicobacter pylori
