Protein

Poly(A) polymerase I

Gene

pcnB

Organism
Escherichia coli O6:H1 (strain CFT073 / ATCC 700928 / UPEC)
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

Adds poly(A) tail to the 3' end of many RNAs, which usually targets these RNAs for decay. Plays a significant role in the global control of gene expression, through influencing the rate of transcript degradation, and in the general RNA quality control.UniRule annotation

Catalytic activityi

ATP + RNA(n) = diphosphate + RNA(n+1).UniRule annotation
