Regulation of the molybdate transport operon, modABCD, of Escherichia coli in response to molybdate availability.

Journal of bacteriology - 1 Feb 1995

Rech S, Deppenmeier U, Gunsalus R P

Abstract excerpt

The mod (chlD) locus at 17 min on the Escherichia coli chromosome encodes a high-affinity molybdate uptake system. To further investigate the structure and regulation of these genes, the DNA region upstream of the previously identified modBC (chlJD) genes was cloned and sequenced. A single open reading frame, designated modA, was identified and appears to encode a periplasmic binding protein for the molybdate...
