VbhT Fic protein from Bartonella schoenbuchensis in complex with VbhA antitoxin and ATP

Template:ABSTRACT PUBMED 23738009

Function

[VBHT_BARSR] Toxic component of a toxin-antitoxin (TA) module VbhT-VbhA. Adenylyltransferase involved in virulence by mediating the addition of adenosine 5'-monophosphate (AMP) to specific residue of host GTPases. The resulting AMPylation affects GTPases, impairing actin assembly in infected cells. [VBHA_BARSR] Antitoxin component of a toxin-antitoxin (TA) module VbhT-VbhA. Acts by inhibiting the adenylyltransferase activity of VbhT; competes with ATP-binding and prevents productive ATP-binding to VbhT.
