Exoribonucleases and Endoribonucleases

EcoSal Plus, 2004
This review provides a description of the known Escherichia coli ribonucleases (RNases), focusing on their structures, catalytic properties, genes, physiological roles, and possible regulation. Currently, eight E. coli exoribonucleases are known.

Escherichiacoli mutants deficient in exoribonucleases

Biochemical and Biophysical Research Communications, 1976
Abstract Strain S296, isolated by screening 2000 colonies after nitrosoguanidine mutagenesis, yields extracts with less than 1% of wild-type RNase activity against ( 3 H) poly(U). Unlike other E. coli strains, S296 grows with a doubling time of about 2 hr., both in nutrient broth and in minimal medium, and at 30°, 37° and 42°. The strain retains

A microsomal exoribonuclease from rat liver

Biochimica et Biophysica Acta (BBA) - Enzymology, 1979
A exoribonuclease has been purified from the microsomes of rat liver. The enzyme had an apparent molecular weight of 80 000-83 000 and produced, via a processive mechanism, 5'-AMP as the only product from poly(A). The degradation was found to proceed in the 3' to 5' direction.

An exoribonuclease in bovine brain

Brain Research, 1975
An exonuclease which degrades RNA to yield 3′-mononucleotides has been purified 300-fold from an acetone powder of bovine brain white matter. The enzyme preparation does not contain detectable quantities of RNase A, DNase, 2′,3′-cyclic phosphodiesterase, 5′-nucleotidase, and acid and alkaline phosphatase activities and requires sulfhydryl compounds for
