Vibrio cholerae iron transport: haem transport genes are linked to one of two sets of tonB, exbB, exbD genes.

Molecular microbiology - 1 Sept 1998

Abstract excerpt

Vibrio cholerae was found to have two sets of genes encoding TonB, ExbB and ExbD proteins. The first set (tonB1, exbB1, exbD1) was obtained by complementation of a V. cholerae tonB mutant. In the mutant, a plasmid containing these genes permitted transport via the known V. cholerae high-affinity iron transport systems, including uptake of haem, vibriobactin and ferrichrome. When chromosomal mutations in exbB1 or...
