Disease relevance of orf4

The LysR-type transcriptional regulator VirR is required for expression of the virulence gene vapA of Rhodococcus equi ATCC 33701 [1].

High impact information on orf4

The att locus contains nine open reading frames homologous to arginine and beta-lactam biosynthetic genes. att gene expression is transcriptionally induced by leafy gall extracts, but not by extracts of uninfected plants, and depends on the attR gene that encodes a LysR-type transcriptional regulator [2].
The pathogenicity island contained a LysR family transcriptional regulator and a two-component response regulator upstream of six of the vap genes [3].
The aim of this study was to determine whether the LysR-type transcriptional regulator VirR, which is encoded by the virulence plasmid, is required for the expression of vapA [1].
The cadR gene was inferred to encode an AraC/XylS type of transcriptional regulator from its deduced amino acid sequence [4].
The putative regulator of catechol catabolism in Rhodococcus opacus 1CP--an IclR-type, not a LysR-type transcriptional regulator [5].
