TABLE 2.

Base changes in mutant alleles found in YB955^a

Allele	Position of mutation (bp)	Type of mutation	DNA change	Result of mutation
hisC952	450	Transition	C→T	Asp→Aspb
	799	Transversion	T→G	Tyr→Aspb
	952	Transition	C→T	Gln→stop (amber mutation)
metB5	346	Transversion	G→T	Glu→stop (ochre mutation)
leuC427	427	Transition	G→A	Gly→Arg (missense mutation)

^aMutant alleles found in strain YB955 and the changes in the DNA sequences of the mutant alleles compared to the published genome of B. subtilis (http://genolist.pasteur.fr/SubtiList).

^bThese point mutations in the hisC952 allele do not play any significant role in the inactivity of the gene product. These two changes may actually represent errors in the published genome.
