FIG 3.

Single nucleotide polymorphisms (SNPs) identified upstream of the arcA1B1D1C1 ATG start site. (A) Schematic representation of the S. aureus JE2 native arginine deiminase operon (arcA1B1D1C1R1) and the upstream native argR1. (B) Nucleotide sequence of the native arc operon region located upstream of the arginine deiminase (arcA) start site. The sequence in light gray represents the region where SNPs were detected. Predicted Arg boxes and cre site are underlined. RBS, ribosome binding site. (C) Identification of Parc1, Parc2, and Parc3 SNPs (noted in the light gray region in panel B) compared to WT JE2. The base pair changes are shown in light gray. (Adapted from reference 64.)
