2-D gels of the crosslinked DNA fragments from ΔruvAB strains.

A) 2-D gels of the crosslinked 18-24kb OP, 24-30kb OP, Chi-9kb OD, 9-15kb OD, 18-24kb OD and 24-30kb OD fragments from ΔruvAB strains containing the palindrome, grown in the presence of 0.2% arabinose for 60 minutes. B) 2-D gels of the crosslinked central, Chi-9kb OP, 9-15kb OP,18-24kb OP, 24-30kb OP, Chi-9kb OD, 9-15kb OD, 18-24kb OD and 24-30kb OD fragments from ΔruvAB strains containing the palindrome, grown in the presence of glucose. The strains used were DL7272 (ΔruvAB Chi-Chi), DL7253 (ΔruvAB Chi-9kb OP), DL7259 (ΔruvAB 9-15kb OP), DL7270 (ΔruvAB 18-24kb OP), DL7271 (ΔruvAB 24-30kb OP), DL7251 (ΔruvAB Chi-9kb OD), DL7258 (ΔruvAB 9-15kb OD), DL7261 (ΔruvAB 18-24kb OD) and DL7262 (ΔruvAB 24-30kb OD). OP and OD mean origin-proximal and origin-distal sides.
