FIG. 2.

Amino acid sequences of protein X and the corresponding ORF on the E. coli chromosome. EvgA-induced protein X was eluted from an SDS polyacrylamide gel, and then its amino acid sequence was determined with a peptide sequencer. (A) The 10 sequenced amino acid residues are depicted as bold capital letters. The corresponding sequence encoded by the yfdX ORF is shown in the lower row. (B) Series of ORFs close to evgAS and yfdX in E. coli chromosomal DNA.
