Protein attributes

Sequence length	254 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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.
Subunit structure	Homodimer By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Contains 1 DRBM (double-stranded RNA-binding) domain. Contains 1 RNase III domain.
