In fact, nothing did happen, but Dr Wang was not convinced that this proved the ball-and-chain hypothesis.
Indeed, Dr Wang tried that by switching an amino acid in the plug for a larger one.
So, Dr Wang concludes, it looks as though the ball-and-chain model is wrong and the rod model is right.
According to Dr Wang, this approach could be used to create strains of bacteria capable of producing whole hosts of odd amino acids.

Dr Wang is seeking to identify specific genetic traits that make women more likely to give birth to a low birth weight or premature baby.
To create a new genetic instruction, Dr Wang's team needed not only to identify which new word they wished to add but also to find something that would carry it and to glue the two together.
"It gives you a little kick so you feel okay and don't have to look for food, " says Dr. Wang.
Though Einstein's framework remains intact so far, "the study is significant for the way observations by astronomers are helping to identify new, extreme cases" to test his general theory of gravity, said Dr. Wang.
If Dr. Wang's previous studies are any indication, he will see that a test subject's striatum, a sort of communications hub inside the brain, has fewer dopamine receptors than the striatum of someone with normal eating habits.
Dr Schultz and Lei Wang, a researcher at Scripps who works with him, have made progress down this path.
