Plasmid pRiA4b, Orf3-like domain

InterPro entry
Short namePlasmid_pRiA4b_Orf3-like
Overlapping
homologous
superfamilies
 

Description

Members of this entry are similar to the protein product of ORF-3 (
Q44206
) found on plasmid pRiA4 in the bacterium Agrobacterium rhizogenes. This plasmid is responsible for tumorigenesis at wound sites of plants infected by this bacterium, but the ORF-3 product does not seem to be involved in the pathogenetic process
[1]
. Other proteins found in this entry are annotated as being putative TnpR resolvases (
Q9LCU7
,
Q50439
), but no further evidence was found to back this. Moreover, another member of this entry is described as a probable lexA repressor (
Q7UEI4
) and in fact carries a LexA DNA binding domain (
IPR006199
), but no references were found to expand on this.
