Table 2. SELEX-chip screening of Lrp-binding sequences: Lrp regulon genes involved in transport and metabolism of amino acids.

The Lrp regulon genes involved in transport and metabolism of amino acids, tRNA, tRNA charging and rRNA are listed. The number of the whole set of genes involved in those functions is shown in Whole set column. The number of genes identified by SELEX screening is shown in the SELEX-chip column. The number of genes listed in RegulonDB (Salgado et al., 2006) or ChIP-chip analysis (Cho et al., 2008) is shown in the DB+ChIP-chip columns. Percentage shows the coverage of the whole set of genes.

Function	Whole set	SELEX-chip (%)	DB+ChIP-chip (%)
Transporter	43	35 (81)	24 (56)
Metabolism	128	114 (89)	41 (32)
tRNA	85	17 (20)	10 (12)
tRNA charging	24	6 (25)	1 (4)
rRNA	21	9 (43)	21 (100)
