Protein

RNA 3'-terminal phosphate cyclase

Gene

rtcA

Organism
Escherichia coli 907672
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the conversion of 3'-phosphate to a 2',3'-cyclic phosphodiester at the end of RNA. The mechanism of action of the enzyme occurs in 3 steps: (A) adenylation of the enzyme by ATP; (B) transfer of adenylate to an RNA-N3'P to produce RNA-N3'PP5'A; (C) and attack of the adjacent 2'-hydroxyl on the 3'-phosphorus in the diester linkage to produce the cyclic end product. The biological role of this enzyme is unknown but it is likely to function in some aspects of cellular RNA processing.UniRule annotation

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.Imported

Catalytic activityi

ATP + (RNA)-3'-(3'-phospho-ribonucleoside) = AMP + diphosphate + (RNA)-3'-(2',3'-cyclophospho)-ribonucleoside.UniRule annotation
