Sulfurous Ping-pong In The Urinary Tract

Entirely new protein structures are very rarely found to drive known biochemical processes. But molecular biologists have just succeeded in finding an example. They studied the protein ASST, present in pathogenic E. coli bacteria, which cause urinary tract infections. In addition to an entirely new structure, the researchers found a transfer mechanism similar to ping-pong, whereby the "ball" is held a previously unknown manner.
