FIG. 1.

Predicted amino acid sequences of the NspA protein of N. gonorrhoeae B2, N. gonorrhoeae FA1090, and N. meningitidis 608B (28). Differences are indicated by the one-letter code, and identities are indicated by a period. Evaluation of the identities between these sequences indicated that these three proteins are highly similar, with a global identity of 93%. Sequence analysis revealed the presence of an additional amino acid residue (glutamine) at position 73 for the NspA protein from N. gonorrhoeae FA1090.
