Ribonuclease III: new sense from nuisance
International Journal of Biochemistry and Cell Biology, 2002RNases play an important role in the processing of precursor RNAs, creating the mature, functional RNAs. The ribonuclease III family currently is one of the most interesting families of endoribonucleases. Surprisingly, RNase III is involved in the maturation of almost every class of prokaryotic and eukaryotic RNA.

Review: Non-canonical role of Drosha ribonuclease III.
International Journal of Biological Macromolecules, 2023The typical function of Drosha is participating in cleaving pri-miRNA, the initial step of miRNA biogenesis, in the nucleus. Since Drosha has a double-stranded RNA-binding domain and two RNase III domains, when it binds and/or cleaves other RNA species ...

Ribonuclease III is involved in motility of Escherichia coli [PDF]
Journal of Bacteriology, 1978 Mutants of Escherichia coli deficient in ribonuclease III are nonmotile. All transductants and revertants that regained ribonuclease III also regained motility, and all transductants that remained or became rnc are nonmotile, although only some of the revertants that regained motility also became ribonuclease III+.

Biochemical properties of Bacillus Calmette Guerin ribonuclease III
Journal of Basic Microbiology, 2016Double‐stranded RNA (dsRNA) is discovered to participate in the regulation of gene expression in both bacterial and eukaryotic cells. Members of ribonuclease III (RNase III) family recognize RNA motifs and cleave substrates at specific sites in a divalent‐metal‐ion‐dependent manner.

Biochimica et Biophysica Acta (BBA) - Specialized Section on Nucleic Acids and Related Subjects, 1962
Abstract The specific activities of total alkaline RNAase, total acid RNAase and free RNAase inhibitor have been followed during the regeneration of rat liver induced by partial hepatectomy. A significant increase in the level of RNAase inhibitor occurred within 12 h of operation and a maximum increase (39%) was observed after 48h.

Specificity of cleavage by ribonuclease III
Biochemical and Biophysical Research Communications, 1976Abstract The specificity of RNase III for various synthetic homopolymeric doublestranded RNA substrates have been examined. Although RNase III appears to cleave all homopolymeric RNA duplex structures, with Poly (U)·Poly (A) as the substrate, the enzyme cleaves the Poly (U) strand much faster than it cleaves the Poly (A) strand.

Characterization of a chlorella virus PBCV-1 encoded ribonuclease III
Virology, 2003 Sequence analysis of the 330-kb genome of chlorella virus PBCV-1 revealed an open reading frame, A464R, which encodes a protein with 30-35% amino acid identity to ribonuclease III (RNase III) from many bacteria. The a464r gene was cloned and the protein was expressed in Escherichia coli using the chitin-binding intein system.

III. THE RIBONUCLEASES OF HUMAN EPIDERMIS
British Journal of Dermatology, 1977Sodium acetate and sulphuric acid extracts of human epidermis can each be separated by chromatographic techniques into three or more fractions with ribonuclease activity. Eight of these fractions were compared with respect to molecular weight, pH activity profile, polyribonucleotide hydrolysis, and activity in the presence of low levels of spermidine ...
