a

Predicted molecular mass (Mr) of putative proteins expressed in strains 26695 and J99. Protein molecular mass values for respective strains are separated by a slash.

b

Owing to a frameshift mutation, expression of this protein in strain J99 is unlikely. Predicted protein molecular mass is based on presumed slipped-strand repair of the frameshift mutation.
