TABLE 1.

Duplication of S14 ribosomal proteins in pathogenic cocci^a

Bacteria	S14 (RpsN)b
	Zn+ form (RpsNa)	Zn− form (RpsNb)
Streptococcus agalactiae	+	+ (3 AdcR box)
Streptococcus pyogenes	+	+ (2 AdcR box)
Streptococcus pneumoniae	−	+
Enterococcus faecalis	+	+ (1 Zur box) + (1 Zur box)
Staphylococcus aureus	+	+ (1 Zur box)

^a Protein homologs were searched by Blast-P analysis using RpsNa and RpsNb proteins of S. agalactiae A909 as queries against species genomes available in the NCBI database.

^b Candidate zinc repressor binding sites, defined by an AdcR or Zur box, in the upstream region of the genes with presence denoted by “+” and absence denoted by “−.”
