General annotation (Comments)

Function

Digests double-stranded RNA. Involved in the processing of primary rRNA transcript to yield the immediate precursors to the large and small rRNAs (23S and 16S). Also processes some mRNAs, and tRNAs when they are encoded in the rRNA operon By similarity. HAMAP-Rule MF_00104

Catalytic activity

Endonucleolytic cleavage to 5'-phosphomonoester. HAMAP-Rule MF_00104

Cofactor

Mg2+ By similarity. HAMAP-Rule MF_00104

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_00104

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00104.

Sequence similarities

Contains 1 DRBM (double-stranded RNA-binding) domain.

Contains 1 RNase III domain.
