IcmF family protein TssM exhibits ATPase activity and energizes type VI secretion.

The Journal of biological chemistry - 4 May 2012

Ma Lay-Sun, Narberhaus Franz, Lai Erh-Min

Abstract excerpt

The type VI secretion system (T6SS) with diversified functions is widely distributed in pathogenic Proteobacteria. The IcmF (intracellular multiplication protein F) family protein TssM is a conserved T6SS inner membrane protein. Despite the conservation of its Walker A nucleotide-binding motif, the NTPase activity of TssM and its role in T6SS remain obscure. In this study, we characterized TssM in the plant...
