Taxonomic identifier

83333 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Escherichia

Protein attributes

Sequence length	1061 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Matures 5S rRNA from its precursors from all the rRNA genes. It also cleaves RNA I, a molecule that controls the replication of colE1 plasmid DNA. It is the major endoribonuclease participating in mRNA turnover in E.coli. It initiates the decay of RNAs by cutting them internally near their 5'-end. It is able to remove poly(A) tails by an endonucleolytic process.
Catalytic activity	Endonucleolytic cleavage of single-stranded RNA in A- and U-rich regions.
Subunit structure	Organized into a structure (processome or RNA degradosome) containing a number of RNA-processing enzymes.
Subcellular location	Cytoplasm.
Sequence similarities	Belongs to the RNase E/G family. RNase E subfamily. Contains 1 S1 motif domain.
Sequence caution	The sequence AAA23443.1 differs from that shown. Reason: Frameshift at position 796. The sequence CAA38206.1 differs from that shown. Reason: Frameshift at several positions. The sequence CAA47818.1 differs from that shown. Reason: Frameshift at position 1003.
