Published in Proteomics Weekly, September 3rd, 2007

Current study results from the report, "Mutation of a key residue in the type II secretion system ATPase uncouples ATP hydrolysis from protein translocation," have been published. According to recent research from Taichung, Taiwan, "Membrane-associated ATPase constitutes an essential element common to all secretion machineries in Gram-negative bacteria. How ATP hydrolysis by these ATPases is coupled to secretion process remains unclear."

"Here we identified R286 as a key residue in the type II secretion system (T2SS) ATPase XpsE of Xanthomonas campestris that plays a pivotal role in coupling ATP hydrolysis to protein translocation. Mutation of R286 to alanine made XpsE...
