Function
VOPS_VIBPA Adenylyltransferase involved in virulence by mediating the addition of adenosine 5'-monophosphate (AMP) to specific threonine residue of host Rho GTPases RhoA, Rac and Cdc42. The resulting AMPylation prevents the interaction of Rho GTPases with downstream effectors, thereby inhibiting actin assembly in infected cells.[1] [2]
