  • a The protein spots were N-terminally sequenced, and the proteins were identified by comparing the N-terminal amino acid sequence to that found on the P. aeruginosawebsite using the BLASTX program (1). The spot numbers correlate with the numbers indicated in Fig. 3. The locus designates the gene number in the genome of P. aeruginosa.

  • b NI, not identified.
