Notes
Implicated in degadation of sRNAs[1]
Cold induction occurs by reversal of post-translational autoregulation. The pnp mRNA leader is cleaved by RNase III, allowing PNPase to repress its own translation. Mutation of Gly454 impairs autogenous regulation without affecting catalytic activity. Mutants have elevated OM vesiculation (McBroom, 2006). Pnp can add long polynucleotide tails to mRNAs terminated by Rho factor (Mohanty, 2006). The overexpression of the Pnp S1 domain suppresses the cold growth defect of quadruple cspABEG mutant strain BX04 (Xia, 2001).[2]
