- This strain may carry an uncharacterized mutation which permits the utilization of N-acetylglutamate as a source of arginine in the presence of an arginine auxotrophic mutation, mutation "X" of ancestor strain.
- spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
