A bacterial gene is known to spontaneously mutate at a high frequency. A study of one mutant gene product shows that the mutant protein made is shorter than the wildtype protein by four amino acids. The wildtype gene has been cloned and sequenced. It has a region of repeated sequences that code alternately for proline and threonine (see below).
