FiwA-like proteins are fertility inhibition factors (FIN), which are employed by plasmids to block import of rival plasmids [1,2]. FiwA is encoded by plasmid RP1 and blocks the transfer of plasmid R388 [3]. A FiwA-like protein called Osa (oncogenic suppressive activity) inhibits the oncogenic properties of Agrobacterium tumefaciens [4]. Osa is structurally similar to the ParB/Sulfiredoxin fold [1]. Osa has been shown to have ATPase and DNAse activities, and can block T-DNA transfer into plants [5,6].
