  • a Protein bands were generated and sequenced as described in Materials and Methods.

  • b As labeled in Fig. 1, lane e.

  • c Gene names are as in the B. subtilis genomic sequence available on the World Wide Web Numbers given are the locations in the genome of regions coding for proteins not previously identified as ORFs. The first and second numbers are those of the first nucleotide of the start codon and the last nucleotide of the coding sequence, respectively.

  • d Residues in the intact protein; the N-terminal methionine of a number of the proteins is removed posttranslationally.

  • e This was the major sequence observed; however, there were also significant amounts of the same sequence but with an N-terminal methionine (∼20% of the total) or beginning at the first lysine residue (∼30% of the total).

  • f Sequence from reference46.
